Hi everyone,

These are the final 8 photos of my restoration of a 1977 H16 and trailer. The first 3 photos are the "before" pics - which are scanned photos and not too clear, but you`ll get the idea. The next five are better. I am currently waiting for my new furling jib before I assemble the rudders and put the boat on the trailer to take her out. I hope you enjoy the photos. After thursday July 14, I will be unable to answer questions again until the first week of August. If you want to see closeups and better photos of the finish, see my previous posting titled "major restorations".

The first photo shows the hulls after washing and again after the first of many complete sandings and a few patches. You can see a few of the holes, past failed repairs and the big chemical burn I was talking about.

note the re-dyed tramp. Unfortunately the shiny new gromets do not show in the photo.

trailer final,


...everything has been re-done on the trailer (as well as the boat). Bolts, bearings...even the hubs and leaf springs were stripped and refinished. I stripped and painted the original u-bolts and brackets too - these were hard to find and replace. Bearing buddies were added as well.

Wow man, that looks great! I repainted my trailer last year, but I didn't go to quite the detail level you did! I just scrubbed it with soap and water and then hit it with several cans of yellow Rustoleum.


Warm regards, Jim

WOW. . . very creative, nice attention to detail. And I thought mine looked good painted black.

Jaime, Will and Newbie,

Thanks very much for the compliments, they are appreciated. As for the "attention to details", I am a stickler in that regard. But to me, that is where the beauty of the job resides. It is nice when others notice that.

As for "how long" it took me. Well, I picked up the boat and trailer on Jan. 14 of this year. I worked on it during the evenings - after the baby went to bed - for the most part. The only daytime work I was able to negotiate was on 3 separate weekends. These were reserved for priming and painting (and acid-stripping in the case of the trailer). These jobs had to be done in a continuous manner, and my over-worked wife was able to accommodate. The actual painting is the easiest, most rewarding and sometimes most stressful part of the job. If a single run or sag occurred in the paint, I wet sanded the entire coat and started again - I just wasn`t willing to sacrifice a perfect job. That is how I achieve personal satisfaction in this type of work - although it drives my wife and friends nuts.

Over the past seven years, I have tackled some bigger projects. However, with a new baby in the house, I needed a smaller project that I could work on at home in the garage - not an easy criteria when one loves to work on boats. I have some sailing experience, and I have always loved the look and the idea of a performance catamaran. In my opinion, the Hobie 16 is the most attractive of them all - bar none. With its beautifully up-curved hulls, heavy aluminum castings and elegant pylons supporting the raised trampoline, I find the H16 almost irresistable. I am sometimes a little surprised when I hear enthusiasts talk about all the great attributes of the H16 but forget to mention this fact. To me, boats can be (and should be) a thing of beauty. And, if I can say one thing about the H16 for certain, the original designers believed this too.

In any event, I will be away for two weeks after today. Following that, I am willing to share everything I did with whoever is interested - and I hope there are some who are interested ...There are a pile of oldies but goodies out there that are in need of some TLC.

Dave

really interesting thread. i've got a 1984 16 that needs some work on the hulls (soft spots, assorted dings, worn bases - repainting!), so i'd be very interested in reading some detail on what you did to your boat.

Great job Dave. I'll prob try a tackle my H16 this fall in a similar fashion as you. I have no previous experience however in hull restoration. Have you already posted an outline of your steps, products, techniques? If so - thanks and where? If not, any chance? Thanks Dave

Gavin & CatRon,

Thanks for the compliments and the interest. Here is a list of my steps in a general sense. I will be glad to answer any specific questions as well.

(1) When I selected an H16 for restoration I looked for a boat with no delamination, good castings and non-skid in good shape. Non-skid is next to impossible to repair to any degree of cosmetic beauty. It generally has to be re-done completely, and since I wanted a boat that looked original when finished, I didn`t want to re-do any non-skid. As for the rest of the hulls, I really didn`t care how bad they were (mine were bad) because I was going for a total refinish anyway.

(2) The entire boat was disassembled and all hardware was removed from the hulls and supports ...only the pylons remained attached.

(3) No less than 3 detergent scrubs (emphasis on scrub) were performed on absolutely everything. All stainless hardware was washed / cleaned with a de-scaler and then polished. All aluminum casts were scrubbed with straight muriatic acid and abrasive pads (using care not to expose anodized parts to the acid). After this, they were cleaned and polished with an aluminum cleaner containing a polishing grit. All anodized aluminum was cleaned (gently) with the same technique but without the acid.

(4) All gromets were drilled out of the tramp. Then I did two detergent scrubs with a brush followed by two degrease/dewax/de-silicon wipe-downs using a professional product for this type of removal (RM 900 by B.A.S.F). This last step is crucial for anything being refinished and its importance cannot be overstated. I use the technique whereby clean cloths are constantly folded, then wiped, then exchanged - always in one direction only.

(5) The tramp was then re-dyed using a quality automotive vinyl dye (not vinyl paint) and new gromets were installed.

(6) After 2 or 3 detergent scrubs, I used RM 900 on the hulls at least 3 times using the above technique. A scrub brush was used aggressively on the non-skid in addition to the wipe-down method.

(7) Being careful not to touch the hulls with bare hands too much (grease contamination) I proceeded to sand the whole works down with 80 grit and a RANDOM orbital sander. This removed as many scratches and defects as possible. I sanded completely through the gelcoat layer only when absolutley necessary to remove a bulge or defect.

(8) I used vinyl ester resin to patch and fair the small dings and gouges/scratches. Some scratches had to be dug out with a dremel in order to get the resin in for patching. The keels were done with either epoxy and fumed silica as a filler, or the vinyl ester (depending on severity). Just make sure that only epoxy is used if the foam core is exposed because the polyester or vinyl ester will dissolve the foam.

(9) The repairs were sanded smooth (with 80 grit) using either a sanding block or the sander. However, using the orbital sander for this kind of fairing can be difficult and takes a lot of experience to do it well - the block may be better for most. Also, these last few steps were repeated several times (a ton of work) using different types of angled lighting to detect the hard-to-see defects and thus begin another round of repairs. These subtle defects will not be so subtle after the high-gloss two-part polyurethane is ultimately applied.

(10) Once I could no longer find any defects. I progressed my sanding up to 180 grit. Then I rubbed chalkline chalk dust all over the hulls and found many other scratches and pinholes to fix.

(11) After doing the chalk thing twice, I sprayed the hull bottoms down with cheap red auto primer and proceeded to sand all the primer off. The red primer remained in all the small defects I had missed - and there were many. I did this step twice. Then proceeded to 220 grit when everything was finally perfect.

(12) One more degrease/dewaxing as described above.

(13) After building a ventilated paint booth in my garage (using tarps) and wetting the floor constantly to keep dust down, I used compressed air followed by a tack cloth on the hulls. I sprayed on 3 coats of EP-FD epoxy primer by Endura (last coat thinned %15) with wet-sanding between the 2nd and third coat. Followed by 3 coats of EX-2C two-part polyurethane topcoat (also by Endura) with the last coat thinned %15. Note: on the hull tops, only one coat of primer thinned %15 was used followed by the same topcoat application as the hull bottoms described above. I did this because I was concerned that applying too much paint over the non-skid area on the hull tops would ruin the texture of the non-skid. As it turned out, I am very happy with the results. FYI - Each coat of paint/primer on the hull bottoms took about 20 - 22 oz of paint (total per coat for both hulls), and about 10 oz of paint (total per coat) was required for both hull caps/tops. This paint is very expensive, so this last bit of info is important in buying and mixing the appropriate quantities.




Hope this helps,


Dave

Thanks CD. Truly incredible work on your part. You are a perfectionist without limits/bounds.
I'll be doing my hulls after sailing season and will refer to your guidelines I'm sure. Hope you'll be around to bounce ideas/problems off.

Thanks again for putting this kind of detailed info on the net. This is exactly what forums are for - there are thousands of H16 and other boat owners with nicks, scrapes and dings all wondering how the hang are we gonna fix all this. Now we know.

CatRon,

I will be here and will be glad to help - especially when it comes to those nagging little specifics we all run into on these jobs.

Tom,

Good question. I do not know the exact original weight of the boat. However, I added 6 coats to the hull bottoms at 20 oz per coat and 4 coats to the hull caps at 10 oz per coat for a total of 160 oz of paint/primer. The gelcoat I removed through extensive sanding would have to be at least 1/2 that amount for a net weight gain of about 80 oz (5 lbs). This would be a high-side estimate. I suspect my gelcoat removal is actually higher than what I have stated.

Hey CD,

I'm about to start the restoration of a 77 Hobie 16. Regarding sanding the hulls - how did you prepare the non-skid area for painting?

Thank you in advance for your answer.
