I recently aquired a P19 and cant seem to find much info on the boat. I am looking for tips, tricks, modifications and a general sense of how it sails. I have read the literature that says its similar to a Tornado but thats all i have seen. Im just trying to get a general feel for the boat and here others experiences with the P19. I currently sail a Nacra 5.2 so im not new to sailing..Only the P19.

I know how to rig the boat and have the manual. Just looking for overall feel of the boat, its limits, mods, etc

I am on the hunt for a square top for the boat so if you guys have one let me know! I may just buy a new one but if theres a decent priced aquare top i would consider it.

I currently run a spin on my 5.2 and will run a spin on the P19 as well. Im open to spin suggestions...Tornado, F18, etc Im sure one of them would work fairly well and fit.

Welcome to the "Giant Killer" wink

From experience....don't ask how I know....

Sqare tops are the way to go, BUT reenforce your
hulls. Install an internal bulkhead just forward
of the FWD crossbeam, will help with the stress
loads from the increase in dynamic lift. Go with
the F18 or N20 Spin. The Tornado Spin is waaaay
to big.

This is MY opinion....YMMV smile

The T spin is not much different than the I20...infact I believe it's flatter and likely smaller overall in square footage. The I20 rig is 31 ft compared to the puny ~29 ft T rig.

Do a search on here for P-19 MX , and look at that mod. It's definitely the way to go.You can have your pinhead modified to a MX square top if you don't want to buy a new one.
I had the MX rig with a 475 sq ft chute and it was excellent in light air and good on up the scale.
I would say GO with a newer cut Tornado kite over an I/N 20 kite. They are flatter and faster.

ButchG...I will post up a picture of the inside of my hulls. Can you use "Paint" or some other program to show me this bulkhead you speak of? I took the deck off of one side already and planned to slightly reinforce but dont really know where to place the added bulkheads and such.

Im going outside to see if i can get a decent pic in the dark! Ill be back soon!

They should be just far FWD enough to clear the mounting
plates for the forward cross beam thru bolts. Also make
sure the bulkhead has a drain cut out at the bottom to let
any water drain. This does two things, it reenforces the
cross beam stress area as well as stiffening the hulls for
less "walking" when cutting waves. This (I think) was
done on the P19's made after 90 or 91. I know there is an
aft bulkhead on boats made after 90. But I am not sure about
the FWD ones. I had mine done after watching stress
fractures appear on two P19's in my area that went to an
MX rig.

Mr. Dobbs is correct...and I stand corrected. The spin I got
was a tornado spin for a T sailor made by Smythe. BUT, it
turns out it was a special order oversize kite...which I am
having cut down for controllability.

A square top main, with a standard size jib and a 24 to 26
square meter spin will bring your D-PN to 64 and change.
Sailed properly (which I am still learning to do) it will
wax N20's....seen it done smile

Ok just went outside to take a pic and my shop light is burnt out so no pic yet. So is a F18 chute too small? I keep hearing that F18's can carry a chute a lot higher than a N20. Is this simply the cut of the chute or the size? I am very interested in making this a fast boat so a chute is a must.

My main is dacron so i would think it may be smarter to hold out for a mylar or pentex main rather than making the original a squaretop?

So how would you compare the P19 with Chute and SQtop to a F18 and N20? Im just curious if this old boat can hang with the newer hot rods? Assuming all the boats have nice mains and chutes with equal sailors. I bought the boat based on what i have been told by others but wonder how accurate these statements are. Everybody i talk to says its a fast boat?

There is a whole chapter in "Catamaran Racing for the 90"s" on the Prindle 19 by Randy Smyth. Won't help you on the spinnaker part, but should with setting up rest of boat.

if i recall correctly, Tornado masts are 31'
i sail a 5.5 with a 30' mast. i started with a H Tiger spin.. it fit ok but my pole was pretty high.

I now fly a T spin and my pole sits a little low and i have an inch of downward pre-bend in the pole.. and my spin luff is JUST barely tight enough..

I doubt you could rig it on an 29' stick.

I have sailed the P19,.. it was great.. i am sure you will enjoy it when you get it out.

We've got 1 P19 on our lake. It is the fastest cat I've seen. I'm sure the majority of that is the skipper, but its still quite impressive.

The MX package is definately the way to go. Glaser sails has a very good guide for rig tuning and sail adjustment. It's a fast and forgiving boat. I didn't realize how resistant it was to pitchpoling until I sold it and bought a Blade. I never used a spin on it but there's a lot of spaghetti on it with the barber hauler, 4-way jib lead adjustment etc... The newer style rudders are much better.

I have two sets of rudders...One set is the 18 Square tip type and the other set is a rounded rudder. I assume the rounded tips are the newer model?

Hi Turbo Cat,

I too have a P19, since 1991, you may wish to research some of my past posts here on "Cat Sailor" where I have discust the P19 and some modifications for a "MX" rig for strength and also the "new" eliptical tip rudder blades .... and how to repair them when they split from the rudder head on down ....

Wait until the first time when you are on a screaming reach .... and you are making rainbows .... awesome!!!!!!


Hey Todd,

I was at Tred Avon YC yesterday for a Junior Regetta ... as I stood there I could just visualize the beach full of cats and the anchorage full of boats after the NASS Race ... the picture w/ my P19MX in it is still hung in the Entrance Way in the lobby. Hope you guys are coming ... see you then

That beach still covered in pea-gravel and oyster shells?

I'd pull my laser up on that beach no problem, I'd cringe when pulling the 20 up on it smile

I went back and did some digging through your post's. I went through all 31 pages and came up with the following:

I didnt look at each post so im sure i missed some info. I looked at the items with P19 in the title and found the threads i posted above. Anyway you can link the "Structural mods" you were speaking of?

Thanks
Ted

I am thinking that Smyth sails are the way to go since he had a hand in designing the boat from what ive read. I am sure he has the most experience with the P19 sails? I have Smyth rags on my 5.2 and love them.

Tornado stick is under 30'...29 and change. The max luff length on the spin is also a factor of where the halyard block sits alone the mast relative to the tack block on the pole, the pole length also contributes (4 meters from tack block to front of beam is the limit) and finally mast rake.

The F18 chute is smaller and flatter...so it will perform better sailing closer to the wind. This can make it fast in races like hte Tybee where you're broad reaching all day long. But, on proper windward/leeward courses, the N20 is faster at deeper angles, and the Tornado faster still. Though the T spin is not cut deep like the old cut of the N20. I think the superior downwind (& up) performance of the T comes mainly from the extra beam.

The P19 is a mini Tornado...hull shape & bow design are nearly identical to the T. Rigging is straight off the the classic T. Even has centerboards like the T, though they appear to be even less capable then the relatively poor performing blades of the T.

I once hopped aboard a P19 for a short sail off the beach with it's new owner. I was impress with how similar it felt to the T. Within a few minutes we were the fastest boat moving that day, passing all comers including a 20 ft Mystere and several Hobies and even two rather beat up/delapidated old Tornado's.

How did you get the deck off?. I recently heard some cracking noises while righting my P19 aft of the centerboard well. I think it was delaminating inside, however, no way to check it it out and if thats the case then I am looking at also removing the deck which Im not looking forward to do.

I recently set the boat w/ an F18 spinnaker and end pole snuffer, I have been loooking for a while for Tornado spinnakers/mainsails but no luck. F18 parts are more readily available. The main problem I had was the attachment of the support pin at the front crossbar. The pin (I think its a nacra standard) has a base with 4 attachment points, but due to the mast base casting it cannot be placed at the beam center. I secured it with two screws on the top two holes tapped into the the lower portion of the casting. For a pole Im using discarded Sunfish spars I can get free from a local sailing club (learned that trick while reseaching the P19 on this site), however I have gone through two already and I am currently searching for a windsurfing mast.

Good luck

VMG is correct. I used a Putty knife with a thin blade. I tried several tools and the thin putty knife worked the best for me. I started at the front and worked my way backwards. It came off pretty well and didnt get too messed up. You can order new decks from Performance for $98 each. I ordered new ones rather than making my own since i dont know alot about glass. After i reinforce the hulls im thinking of smoothing the bows. My 5.2 has had the bow decks filled and its stiffer than stock and looks great! I am still trying to decide if i want to go this direction though because once they are filled and smoothed future repairs are much harder since you cant just remove the deck and order a new one.

According to Tornado.org waterline to top of mast max is 9800mm or 32.15 feet. What does the typical tornado measure from waterline to mast base?

That is PER side. $98 for each deck

The decks am assuming are three part?. Forward of the front beam, center section and the little square portion aft of the rear beam. For $98 I think its a good price. I am also guessing theres a lip or surface where you can lay the new deck and epoxy to the hull.

I would hate to think he is talking the front only? They probably have to make them special for this order.

The front decks are $98 each. These are the decks in front of the crossbar. 1 piece $98. They dont stock these old parts so yes they are semi special order. Apparently they still have the molds and make them per order.

PICS WILL BE UP SHORTLY!!!

So my question is should the boat be braced like the front between the rest of the bulkheads? I would assume not since it wasnt designed that way but i want this boat to last me a long time so my ears are open. I dont want to take any shortcuts and want to do it right, do it once, and be done with it. I have another boat to sail so this project will not be rushed. Give me your opinions and let me know what u think.

I have been on other prindles that have flexy decks so i intend to add some bracing of some sort to support the deck more than it is now. The decks are held on by the edge only and seem to flex when stepped on. I would rather the decks feel solid and firm with little to no flex.

I made the under deck support on my Stingray by putting 3 inch strips of divinacell foam inside the hulls just under the lip. I cut them longer than the gap so they flexed up to match the deck then put a bit of tape on with resin as I put the deck on. I also added another layer of divinacell foam under the decks.
Since you are doing a special order have you considered asking them to do a double layer of foam or layer of carbon underneath the decks? The lips are firm enough, keep an eye on the weight your adding.

Something else to think about, and maybe I didn't catch this earlier, and that is put in some tangs for you spinnaker bridals similar to what is being used on the Inter boats.

Check out the photo section on the Tornadocat Yahoo forum...there's a nutty Aussie rebuilding his glass T boat in his living room. He's added lots of reinforcing including deck frames and gunwale stringers.

Hi TurboCat,

I'm not very good w/ computers, so I don't know how to "link" ..... but if you pull-up my posts and then look only at the P19 related ones you should find out what I've learned over the years. Please pay close attention to the posts about reinforcing the front crossbar (internally) as the number of front crossbars failing at the point where the dolphin striker ends is increasing as the aluminum crossbars are experiencing "fatique" failures.

To "stiffen" up the foredeck I would suggest installing a vertical web(s) on the underside of the deck before re-installation of the deck ... you will need to notch the bulkheads for clearence. Yes, I would install a subdeck in the front crossbar area ... this will prevent the bows from toeing in (feel for whipples/waves on the hulls just in front of the front crossbar on the in-board side). I took a simplier route by using a Nacra 6.0NA Bowfoil to prevent "toe-in" but this limits the angle of the spinpole to a very low attitude/angle. But it does works w/ a Tornado 25sqM chute since you need the luff length.

Send me a "PM" here on this forum and I'll answer your questions. FYI: Todd (Team Cat Fever)also has just a wee bit of experience on a P19 before he became a traitor and sold his to purchase a N20 .... we had many good times racing against each other (and drinking Beer) for a number of years.


Hi Tad (Thad?),

No, the beach at Tred Avon is not Oyster shells any more ... it is SAND ... it does have a nice angle of pitch, nothing to bad though. Now the parking lot and the pathways around the clubhouse are gravel ... ooch-ouch ... So we'll see you in September???? I maybe on Triple Threat aqain, if we get the spinpole that we tore off the deck in the "Around Long Island Race pounding through some big seas re-installed and fix the hole in the deck also. Todd saw her when he came up to Solomons Island a few weeks back for "The Screwpile" Regatta ... ask him what he thought about her. If not I'll be back on either my TheMightyHobie18 or P19 depending on who is crewing (most likely the P19)

Not sure where the 29' measure comes from on the T mast. I measure from the top to the bottom of the mast section (not including the base) of a marstrom untapered aluminum section, 30'- 10 3/4". Now the luff of the sail may be around 29' but mast is about 31'.

The T chute and the N-20 chute may be the same area but the N-20 is a class sail built by one manufacturer. The T sail can be made flat or full and by anyone as long as it measures in.

I stand corrected. For the carbon T, class rules state:

Mast Length - -
Upper point height - 9294 mm = 30.49' Note this refers to the upper measurement band max height (head of sail cannot be above this line), not the overall length of the mast.

I think I was recalling the dimension between the upper & lower measurement bands, which is 8915mm or 29.25'.

What material should i use for the sub decks? Foam wrapped in glass i assume. Attaching them to the inner hull is pretty self explanatory.

Im thinking a polyester resin would be favored over epoxy?

Use epoxy but tell anyone that wants to know thats its polyester, they may start waving some ancient class rule at you if you race it!

Yes it is. I planned to add these so i could avoid the whole "Drill & Fill" technique commonly used for the spin. I have done the drill & Fill and it works fine..But this will look much cleaner and probably hold up alot better. Keep the ideas coming! I almost have my game plan down.

On a non structural/Glass note: I was wondering about installing grommets in the tramp and a line under the tramp similar to my 5.2 and getting rid of the jib system on the P19. It really clutters up the tramp so im sure others have done something to declutter the tramp. Any ideas or pictures?

Which size jib do you plan to use?

The MX jib was a solution for down wind sailing in sloop mode configuration... If you plan to use the spin for down wind sailing... then... no need for the oversized jib. (it actually would hurt you) You also get to dump the barberhauler system.

Maximizing the jib for upwind sailing means you will go with a higher aspect jib which allows you to put self tacking hardware on the front beam and clean the tramp up considerably.

If you are keeping the standard jib... then you can consider sheeting to a couple of points on the tramp.

if you plan to use the mx or standard jib and replace the inboard sheeting system with grommets... Make sure you upgrade the tramp material to handle the loads and have a means to really tighten it up. The Aussies used a really thick tramp mesh and were able to really tighten the tramp up from one side and the rear without pulling it out of the boat on the Tornado. If you don't get the tramp almost rigid... energy is lost from the jib stretching the tramp on each puff.

Finally, you should consider your sheeting point for the spin on the boat. It will be determined by the spin cut and luff length. Possibilities include the shroud attachment point. the existing jib track or the tramp lacings.

Reinforcing the front cross beam is very important. The shape and the size of the beams on modern spin boats are much bigger then the P19 section. Big beams work to keep the boat stiff. You might consider a new third party front beam since you have the decks off already. A carbon tube from Australia is remarkably cheap (i am told) and could solve your problem.

Note the comment about finding room to attach a spin pole end fitting on the front beam.

Note.. the buoyancy of the P19 bows is not great and so keeping weight out of the nose is important.... not having to go with a nacra type bow foil is important.

Finally... every P19 I have sailed had these cracs in the deck in front of the dagger board wells. Everyone reports that this fix is a pain in the butt. Take a look at this spot.

Lot of work ahead... glad you enjoy it!

Mark,
I dont have the cracks in front of the dagger wells. All is well there. I am considering the standard jib for now in the beginning. I may actually wait to install the spin and just get used to the way the boat feels and handles at first. However any mods that need to be done for the spin will be done now so i dont have to do anything twice.

I like the idea of a carbon tube but that doesnt sound cheap. Do you have any info on these tubes? I do have a extra set of crossbars if that helps? I read earlier that Hmurphy used a spare cross bar cut into pieces inside his existing beams.

There is a local guy that has his jib sheeted to the tramp and im supposed to be getting pictures of his set-up.

Yep... it's all about the master plan.
Adding the full subdeck will help the fiberglass with the spin.

Harry's reinforcement of the cross beam will stop it from breaking but won't help the structural problem of the bows pinching in.... He used the bow foil for that issue... tradeoff weight on the nose, cost and hindering the spin pole location.

I would decide on your spin pole and spin.
The higher you carry the spin pole... the less load you have on pinching the bows. but with a fixed luff length of the spin you obtain... you have to go higher and higher on the mast for the spin bale. The Tornado chute fits on the Prindle with a long pole... The F18 chute might be a better choice. I thought the T chute was a bit too much for the boat.... with out the T's beam... you really only had one gear down wind on the 19 which was a little deep.

At some point the costs could push you to a new boat or a new to you modern spin design.

I like the idea of a carbon tube but that does'nt sound cheap. Do you have any info on these tubes? I do have a extra set of crossbars if that helps? I read earlier that Hmurphy used a spare cross bar cut into pieces inside his existing beams.

No info.. Our local A cat builder speced some tubes recently and commented that they were surprisingly affordable.... The right beam plus a dolphin striker solve your bow foil issue.

There is a local guy that has his jib sheeted to the tramp and im supposed to be getting pictures of his set-up.

You can put some reinforcement patches on a standard tramp and put the grommet there and it will work just fine.... How well. (speed and performance tradeoffs) are the issue


just cause it looks like what the tornado is doing... does not make it equivalent.

Also... keeping the standard jib means that you will be able to have some vision to leeward of you... the deck sweeper mx jib... really left a huge hole... tough situation if you want to race buoys'.

I will take alot of pics and will be making a video too. I want to help others out any way i can so this should help. I am going to video the removal of the other deck early next week when the new units arrive. I love taking pics so this shouldnt be a problem! I figure if its well documented maybe some of the old 18-2's and P19's that are sitting there rotting away may get fixed up if they have a decent video and picture album to look at and half way understand what to do.

I cant believe its been 6 months already! Ive been slacking off big time. In August i bought a Yamaha R1 (sportbike) and have been riding it as much as possible. The last post on this thread was right about the time i got the bike....Funny how that works.

Back to business!

Last time i posted i think the decks were still n the way. I received the decks from Nacra and was a bit disappointed. When i opened the long cardboard boxes i found the ends of the decks were a bit crooked. The packing job was not great by any means.
[Linked Image]

Now lets talk about the tubes/reinforcement that Nacra said they would add. I am fine with the overall design and think that they are better than the old style. When i removed the decks from the box i pulled out 4 pieces. The reinforcement pieces had completely fallen off one of the decks. Glad that didnt happen in the hull.
[Linked Image]

So at this stage of the game im wondering if i should leave them as they are or revise the design?
If i leave them how they are now i will have to slightly notch the bulkheads so they sit flush. I was thinking about removing the tubes from the other deck too. I could notch the bulkheads and resin and glass them in nice and sturdy if they were off the decks. When installing the decks i can lay resin on the original lip and the new tube at the same time and glue them down. I think they may make a bunch of noise in the hull if i dont glue the tube to the bulkheads. I have to notch the bulkheads either way to fit the tubes so i just figured i may get a stronger bond this way. What do yall think?
[Linked Image]

I have all the materials and am ready to start work asap. I actually sanded on the boat for a while earlier trying to get all the resin and left over glass off the inner lip of the hull. 3 or 4 more hours of tedious sanding on the inner lip and i should be ready to start the next step.

P19s need reinforcement for use with a spinnaker to keep the bows from pinching. I had a couple of them the last of which was very tricked out. Unfortunately, I didn't make any structural improvements. One day sailing to weather the hull snapped in half at the cross beam. Here's a picture taken earlier on that fateful sail.

I have the Smyth Pentex main with foam battens in excellent condition if you are interested.

Why dont you just fiberglass the tubes to the deck?. I'll post pixs of my P19 sunday, its also in a similar situation, but when I removed the deck I also took along with it the hull lip.

The boat is coming along nicely! I took the boat by a local fiberglass/boat repair shop the other day to see what they would charge me to sand the lips and glue the decks down. They quoted me $700 PER SIDE to sand them down and glue the decks on and kept telling me it would take days to sand the lips properly. One hours time, a angle grinder and several sanding discs and i was done with one side! I cant believe it only took an hour. The outside of the boat is faired and ready for paint at this point. Tonight i will sand the other side and prep for the deck installation. I have to go to the local fiberglass supplier today to pick up the Divinycell and more supplies. If i can keep this pace going this thing will be painted and floating in a month or so!

Heres my P19 also with decks removed. I was not able to separate the deck from the hull leaving the lip intact. Now I'll have to find a way to bind them together with epoxy and a thickenning agent. I am adding a bulkhead halfway between the front bulkhead and the bow as I was getting delamination on the inside hull. I think due to standing and walking along the hull to right it

Im not a boat builder and dont know the best solution for your problem...BUT, if i was was dealing with it i would do the following.

Rip a piece of core foam (corecell, Divinycell, etc) on a table saw to about 3 inches wide. Wrap it in glass and epoxy resin. Glue it to the inner edge of the hull creating new lips. Then run a few strips of glass wrapped foam on top of the stringers creating a base for the decks to sit on.

I dont know alot about boat construction so i could be totally off.

MIKE HELP!!!! TheManShed is a true builder and he can point you in the right direction i would think. He has helped me out and doubt he would have a problem giving you some suggestions.

I replied to your PM. Let me know!

After debating how to repair the soft sides opposite the centerboard I just attacked it with a multi tool. You can see the craks on th einterior surface. That portion of the hull is foam with a single fiberglass cloth layer.

Whoa! Your really getting right in there...I assume you know how to repair that? If not i have a good hobie pdf that outlines the process. Can you take a picture of the interior top lip where the tramp rail screws in? Im trying to determine how thick the aluminum plate is and how long it is. Also trying to figure out how deep the rivets go into it. Ive looked at it with a mirror but a pic to compare would be nice.

Those cracks don’t look too good. It looks like it is on the panel that you cut out so the repair will easy to get at. The cracks have to go away you will need to grind the foam out clear through to the outer skin. Make sure you get all of the damaged foam removed then about ½ inch on each side of the crack taper the foam about a 30-degree angle outward towards the inner skin. Then I would lay-up two layers of unidirectional cloth about 6-8 oz weight tying the outside skin to the inside skin. You can fill the void with a bog made epoxy and a filler chopped glass and fill in the void level with the inner skin then lay-up one or two layer of over the patch area to pull it all together overlaying the area by several inches. Look on the outside of the hull my guess if you have kind of damage on the inside you have cracks on the outside also, or maybe it's just soft there.

You need to build a lip for the deck lid. That is going to take some creativity. Looking at the picture the flange needs to be curved in shape. I would make it out of solid glass and you need to try to tie into the top and bottom of the damaged area if you can. You’ll need to grind into the area near the opening to get a good bite into the old glass, perhaps 2 inches. Looking at Turbocat’s picture of the new laminates, I take it you are going to get new laminates? If not, even the old laminates I’d mold off of them. Look at the picture of the new decks as they sit sailing side down there is flange around the edge of the laminate. Use a good quality duct tape and tape off the edges both sides top and bottom. Cut some cardboard from a big box and extend the edge of the flange out several inches as needed to tie into the flat part of the deck, you will need to go further but that will be the next step. Tape the cardboard to the side of the deck that is the actual top as it sails. So as you are looking at the picture in the post you have the upside deck lid (tubes up), tape, the deck lid, tape, cardboard. If you make the cardboard flange you can actually fit it in the hull to check for fit. Once you have your cardboard flange taped down to the deck tape out the cardboard. Wax everything with mold wax it you have it if not a paste car wax. If needed you can make the flange in pieces. I’d lay-up a flange with enough thickness to equal what was there. Now that the flange is made you need to attach the flange to the hull. Make sure you use Acetone or the like to remove the wax and sand some to skuff it up. I like pop-rivets or drywall screws just a few to hold it in place and dry fit everything. Grind and fit as needed. Once everything fits all right, remove the pop-rivits or screws, and glass in the flange you made and overlap it some in the hull on the top and bottom.

There is one other way but it may be more work and that is to cut a few access holes in the inner side of the hull to work through and glass it up directly then patch the holes with flanges. I had to do that with my G-Cat because the deck is one piece. I have some pictures on my website of making a flange repair http://themanshed.net/archived-projects/g-cat-catamaran/?g2_page=2 and page 3.

West systems has CD called How - To Basic application, fiberglass/composite repair, and gelcoat blister repair using their products Catalog Number 002-898 it was free at West Marine for awhile when you purchased some West Systems Products. It is general information for all repair work.

Mike, thanks for the help. As it is, the decks do still mount on to the small remaining lip so I may be able to epoxy the hull to deck without building the lip all around.

For the cracks I started by removing the fiberglass cloth at the cracks around on in and then filling with thickenned epoxy, 1 in strip of fiberglass tape, then two and a 3 in over the previous two. Then two layers of cloth and it seems pretty sturdy.

so no aluminum in there? Thats pretty strange. On older Nacra 5.2's i think that foam piece was aluminum? I figured the rivets and screws would need more to bite into than foam covered in glass.

ferminj, Thanks to your pics we can now see the inner workings of the boat. This is the best P19 thread ive ever seen! With all the pics on this thread it should be easier for the next guy to fix his p19!

Shoot me your email and ill send that hobie repair article

No Al, I think my rivets were a bit loose and I'll have to either epoxy a washer under the accessible ones or fill the hole with epoxy and redrill. My ultimate goal would be a dry as dust hull. The seems sturdy at that part, what I dont comprehend is the 9 or 10 ft between the front xbeam and the bow tip with no bulkheads.

ferminj,

What year were your hulls made????

I believe they added some additional internal reinforcements after the first several years production ... maybe in the 88-89' timeframe???? But I'm not sure since I've never personally seen for myself the internal structure of the later produced boats ... only heard rumors ....

FYI: My boat was produced in 1986.

The detail sanding is taking some time. Im trying to leave the original interior lip intact and in good shape so ive been taking it nice and slow. The foam should be here any day and the other materials are ready to go.

Ferminj,
If you look at your pics and my pics you can see that you have an additional bulkhead in the rear and the spacing is different from mine. Your hull must be a newer hull.

Ill have more pics up this weekend!

OK more pics will be uploaded tonight after work. Ive done alot in the last week but still have a bit to do before this old boat is ready. If all goes as planned this boat will be in the water next weekend.

I plan on rigging the boat back up and sailing it a couple times before the paint job. I want to sail it and evaluate the power before i run out and order a new main and jib. The chute got rigged last night and looks to be in the right position. I made up a line type bail rather than the normal wire bale so hopefully it will last and not pop the line right away.

Ive been playing with ways to stiffen up the beams too so ill post up my ideas and see what you guys think the best angle of attack is. Beam in beam, cnc'd inner sleeves, tigging on a additional pice of aluminum to the top, etc.

I know the last post on this thread was back in 2010. I need some advice. TurboCat, I think we both live in the Houston area. I was sailing Galveston Bay today and it was blowing 20 with gusts and choppy. My 1987 Prindle 19 "I thought" was very solid. It looks like a new boat. The starboard bridle wire tang, the point where it attaches to the hull snapped off. Looks like metal fatigue. It didn't pull through, there is no glass damage to the hull. How do I make this repair? I'm guessing the deck is going to have to come off. I have no idea what this tang has "inside" the hull. I'm also thinking that if the starboard one failed then the port side should also be looked at and replaced. Can I find these parts and how do I make the repairs? Any help is much appreciated. I'm freaking out at the thought of taking it to a glass shop, looks like $$$$.

Thanks in advance

#1 I would look at why there would be metal fatigue? If the bridle is pulling at some new angle other than what it was designed for, then that would have to be addressed. If you want to fix this right you will have to cut some holes in the hull. I like to use a rotary grinder/sander with a 6" wheel you put 36 grit paper on it and grind a hole under and around the broken tang for about 4 to 6 inches below it. That gives you enough room to work and maybe get the broken off tang out of the hull. It also gives you a feathered edge from which to re build the hull. If you can find a fiber optic device and fish that into the hull under the tang, that might help to diagnose the fix too, and see what the best plan would be where to go in, etc.

If you haven't done much fiberglass work yourself you might want to get a book on the subject from the library. One good one is "The Gougeon Brothers on boat construction" or "Fiberglass Boat Repair & Maintenence" also from Gougeon brothers /West System epoxy.

It's no fun, but it's possible.

I don't know anything about the Prindle but the angle of the existing bow tang should give you an idea of how it will be mounted. If its flat verticle it may be as simple as bolted to a bulkhead and that would be a relatively easy fix once in the hull. When cutting into the hull make sure you don't make a cut on top of a bulkhead as you wont be able to get your arm in the hole

My wag is remove the deck say 3" or less one or both sides of tang/bulkhead.
As the replacement/new deck may be easier area to build back vs trying to rebuild the hull.
Corrosion? Look for hairline cracks on ss in the other one.

I have replaced a few, they are shaped like a cross with the horizonal piece shaped the same as where the hull and deck meet. The fitting is glassed in position. I used a 6 inch hole saw (in reverse) on the opposite hull side to gain access. Save the cutout, Ground away the glass removed, installed the new part, held it in place using vise grips on the outside of the hull, glassed in. Repaired the hole using the cutout and a backing.

for backing to reinstall the hole, cut short popsicle sticks and glue them to the inside of the hull to make a "shelf" for the cutout to sit against. Use cloths pins clips to hold the sticks to the hull while the glue dries (epoxy or polyester resin) and be careful not to get any resin on the sides of the opening so your cut-out will fit back in without issue. Then mix up some more thickened resin and put it to the sticks and the edges of the opening (lightly). fit the cut-out back into the hull and rotate it back and forth to squeeze out the resin and get it at the same level as the outer surface of the hull. Tape it into position and let it firm up. With a small ziplock bag, fill it again with more thickened resin and just nip off a corner of the bag with scissors or a razor blade. Use this to squeeze in some more thickened resin around the perimeter of the repair filling the gap between the hull and the plate like icing a cake. This resin should be the thickest of them all - nearly like peanut butter in consistency. Scrape away any excess and let this cure. Then, with a side-angle grinder and a flapper sanding disk, I would sand around the perimeter of the repair you just made and dig into the fresh resin creating a little dished out area to lay in some new fiberglass to join the outer skin back together. Cut a bunch of fiberglass pieces and start to build the shallow U-notch you made back out slightly beyond the outer surface of the hull. Let it cure, sand with palm sander, skim coat with some premium bondo, sand, fill pin holes, gelcoat.

Thanks for the replies guys, I wasn't sure if my question would be seen as this thread was from back in 2009. I posted up again as a new posting, hope this is not a problem. This seems like it is going to be a BIG undertaking and I have no glass experience. I read and reviewed the photos Turbocat posted, it just looks like removing the top deck will give the easiest access but I don't even know if I can still find new top decks. Plus, not even sure how to get the top decks off.

Thanks for the help.

I think going in through the side is a better option. A hole-saw may not provide a large enough hole, you may be better off to use a jig saw and cut the access through the side of the hull, then reinstall the panel you cut out. Removing the decks is really hit or miss...you may break the deck and I really doubt you'll be able to find a replacement....then again, maybe fixing the deck would be easier than the hole option?

If you do use a jigsaw ,set the blade at 45 degrees so you cut the hole like the top of a Jack o' Lantern( \_/ ), then you have a larger stable gluing surface to re-mount the patch back on to. Makes fairing and finishing much easier, as well as a much sturdier repair.

I've removed a top deck before on another boat and it turned into a big job to get it tidy again. I would encourage you to do it through the side as the above posts by experienced people recommend. The more worried about your fibreglass skills the more you should go through the inside of the hull, even if you don't do a very good paint job on your repair nobody will notice it but your decks everyone will see. If you do manage to buy a new deck you need to trust your resin skills to glue it down with absolutely no gaps anywhere or it will suck water and it is very difficult to stop these leaks afterwards

I've done both and getting the deck off without tearing or breaking it is very hard (Apparently too hard for me) if you are going to try and get the deck off you need to use a heat gun and a putty knife ,but not get the glass too hot. The side is easier, will finish better (especially if you do the pumpkin cut) and is less apt to be under as high stress loads as the deck will be. Just make sure you have open access before you cut i.e. not cutting into a bulkhead.

If a man is to be obsessed by something.... I suppose a boat is as good as anything... perhaps a bit better than most.

Aaaa! good point...avoid bulkheads. Cutting into one of those for your access hole has a suck factor of "12".

I agree with cutting into the sides vs. removing a deck. I need to cut into the sied of my N20 this winter and have been studying Jakes repair photos for ideas. Not to hi jack but has anyone ever noticed a thin, soft line in the side just below the no-skid where your heel rides when trapping out?

I've never noticed that on any of the 20's I've owned/worked on. Is it horizontal? There shouldn't be any structural feature to cause that (unless you have a Hobie Tiger-like sub deck for some reason).

It is horizontal and about 16" long. I'm thinking there may be a seam in the foam core here. I'll be cutting in a hole on the inside and likely laying up some carbon in there.

Mine had a 6" fracture when I bought it,. I chased it , glassed it and gelcoated it, seems to be solid so far. It was right behind the rear beam, 6" down.. It was easy to sand and add a layer of glass on the inside through the access port. I got lucky. There was no structural member there.

My 5.0 had a 6" fracture in front of the main beam. right at the top of the long. struct member. same fix. single layer glass hulls so I just fixed from the outside.
