Hi all, sorry for being quiet for a while, as stuff crawls to a stop around Xmas, but things are picking up now. The attached pic's are from Billy & Grahame's project in the North of NZ and they are building 4 boats, 2 for each of their kids. Pictures should be pretty self explanatory and are in sequence. The first boat should hit the water in about 6 weeks....we hope ? For those not familiar with the project, we elected to make foam/e-glass panels that will then be tabbed together in the jig rather than make it from plywood. Cheers RG

Another Update: Roughly speaking, it has taken 1 day to cut the foam templates, cut the foam cores and join them and get 4 panels laid up (3 people). It took another 2 nights of 2-3 hours for 2 people to lay up another 4 panels per night. To separate and trim the panels took 2 people 1 day and get them ready to be tabbed in the jig. In total it took 4.6 sheets of foam to do all twelve hull panels for 2 hulls. First pic is adding the cleats to the frames, these are hard wood so we can staple the hull panels in place. Do not staple into the MDF frames as after 2-3 boats the frames will start to fall apart.  Cheers RG

A couple of pics of the first 2 hull halves done, no bulkheads yet, just the hull panels tabbed together in the jig. We are shooting to have all 4 boats finished/launched at the same time. Cheers RG

Hi,
are there any pics of a complete hull finished?
Looks like an interesting design.

Update: Billy & Grahame now have 4 half shells done (1 boat) and perhaps 1/3rd of the panels laid up for the other 3 boats they are doing. There are 12 panels plus bulkheads per boat, so when you can only layup 4 at a time, it tends to slow things down a bit. With luck, Billy will post a pic of them holding a couple of hull halves together, thats about as close as you'll get to a finished hull pic. Gato, apart from the Class fee of $50, the plans are free. Cheers RG

Hi there, with a bit of experience and liking the comcept we decided that testing two was better than one, then setting up for two just as easy to do four so more people can experience them and we can make more of an impact when we launch. Here's a picture of the two halfs together for those interested.

How about foils, crossbeams, mast, rudder system, trampoline, sails etc? The illustrations shows curved mainbeam, curved traveller track etc. Homebuildt, or can those be sourced on the cheap somewhere?
The foils can be sourced from Billy or John Lindahl in the States (cut down versions of the LR2 boards and rudders), cross beams we just got priced at bending the beams at approximately $40 per set, travellers can be purchased pre-bent, sails & tramp we give you a plan for whatever sailmaker you wish to use, and rudder stocks can be made from aluminium, although we will probably go for molded ones for these boats.

This is a pic of the kids checking out their new boat. So far Billy and Grahame have built enough hull shells for 2.5 boats. The boat now has a name .... Vudu 3.8 and we'll have a website up sometime soon at vuducats.com where anyone can pay their class fee and download the plans in the desired format they want. Cheers RG

Maybe the kids should vote for the names ? It's their boat right ? It should be cool for them not for the grown-ups.

What is the deal with the names? Two F-12's that look like a great start to a class and one is named Dark Side and the other Vudu (sounds like a different spelling of voodoo). How about naming these great little cats something that gives visions of performance sailing rather than the occult? Again...great boats...but the names leave much to be desired.

Bob
Bob, I totally agree.

Then maybe the boat should be LS (Light Side), or FS (Fast Side).
But that is for the other thread. I don't see anything wrong with "Kiwi."

Isn't Tornado a terrible name? A Tornado is destructive, dangerous and, sometimes, mortal. It destroys everything on its path. It is REAL evil.
Vudu, on the other hand, is a type of sourcery that is unlikely to have the power to harm anyone. It is pagan superstition, IMAGINARY evil.
Vudu evokes magic, supernatural forces and phantoms, which is not so bad, considering the video games available nowadays. But real Vudu isn't worse than a real Tornado. Think about it.

Oh you guys are great. I volunteer to be the F12 forum moderator so I can lock this thread before my kids see it  . I'm happy with the black annodised beams but will probably be a bit tricky like Gato with the paint, the only problem I see is touching the paint up. I like the thought of 1 can of paint for all the boats. Scarecrow or RG had you given any thought to a rubber bow protector as I will be loaning my boats to novices, it may stop us sinking a 420 regards.

Hi all,
short update, all the hull halves for the 4 boats are finished now, a couple of boards have been made and the flanges for joining the hulls are being installed. Billy's wife wrote an article for the next Aussie Multihull mag that will be out in the next issue, with luck that will generate a bit more interest.
Jeff....why wouldn't we want to sink 420's ? <grin>
Other than that I think life has generally intruded significantly on boat building recently, but some progress has been made.
Cheers
RG

Sorry Luiz I reckon any bow protector needs to look part of the boat and not mark the skipper as a novice. I'm thinking of putting just a rubber strip on the bow painted the same as the boat to be unobtrusive but if someone has a better idea.
Great to see you've been flushed out and back online again by abuse of your thread RG. Cant wait to see the article and see if it generates some more activity, I don't want to upset the 420's because we may sink them with a below the waterline shot but then I'm the clubs repairer. My biggest concern is kids swimming, with a 420 not a problem, with the F12 the bow is on the waterline and would crack a skull at very low speed.
regards

Not really a fan of bow bumpers. They deteriorate pretty quickly (within a season of regular use) and are only effective for very slow speed collisions.
I've seen Vagabonds (slow speed training dinghies), Pacers (higher speed teams racing dinghies) and model yachts all get holed or get significant damage after a T-bone with the same boat, both to the "T-ee" and "T-er". All had rubber bow bumpers.
Better to reinforce with learners to keep a good lookout and not run into anything. That concept will hold them in good stead for the rest of their lives, as opposed to relying on bow bumpers.

Im with Rolf, most kids are not idiots and hence will do their best to avoid trouble. I think we are worrying too much. I started sailing young and apart from occasionally getting squeezed on a start line or at a mark with a slight bump (gunwhale to gunwhale) I don't think Ive ever hit anyone.

They dont bump much in the current optis, so I see "safety bows" as kind of overdoing it. Hypothermia is a far more likely danger, but I dont think the boat should be designed with that in mind either.

Rolf,
It depends on where you sail. Hypotermia is not a problem in tropical waters, where colisions with swimers are a reality.
In Brasil, for example, it is prohibited to sail or row closer then 100m to shore to avoid colisions with swimers (200 m with engine). Crowded beaches usually have small channels marked with buoys through which jet skis, kayaks, beach cats, etc are supposed to leave and approach the shore.
RG
Kids are smart, especially those who sail, but accidents are more probable when learning than later, whether involving kids or adults.
Sacrifice bows are't present in any competing design, so their absence isn't a disadvantage. On the other hand, they could help build a favorable image of a safe boats for kids.
Along the same line I dream of mast top winglets, not necessarily effective as a go-fast resource, but with enough flotation to keep the boat from turtling. I think their look would help sell the boat to kids while their 'secondary' function would work with parents.
Just my points of view, of course. I can be wrong.

Anyone knows why the number of downloads nearly doubled for the picture of the beam in place? Can it be interpreted as an increase of interest in the F12 in general?

Bob,
beams are 6061, 63.5mm * 3mm and the bend radius is 3.152m. Billy bent his beams to 4.0m as that was the minimum the benders could do, so they aren't quite flush with the deck. Beams are also sized by what we could obtain, 60mm*2mm would be adequate if you could get it.
Cheers
RG

RG,
Is there any information about the chinese serial Vudu production you can advance? Depending on price, specs, etc., I am be interested in buying one for my daughter.
If the final decision is to build one, it will be the round bottom, unstayed mast version.

that looks fast just sitting there, not to mention that they are probably the best looking hulls Ive seen a long while

If you wanted to post 9 pictures, note that the second three were repeated in the third post.
How much would they loose upwind without daggerboards? 2%? More?

Q Sorry Gato, I have absolutely no idea, but based on previous projects I don't think it has been any more time intensive than anything else Ive done. Cheers RG

Luiz, all the pics are actually slightly different :-) As for the boards, I have only ever done one previous cat with skegs and no boards to help guess at the difference....lets just say that I won't willing chose to do another skegged boat Cheers RG

Just wondering if there is any point in building a hard chained hull in foam? It took me five weekends to put the round bilged Tabby together.  Gato, other than a slightly lighter weight (7.7kg/hull before fairing) I don't see much of an advantage since we have a minimum weight. Maintenance & weight gain over time probably favors the foam cored build. Cheers RG

My question was more about the foam construction. If you are building in foam it seems to me that it's both faster and easier to build a round bilged hull. yes, it is easier to build, the attached pic shows how we did the LR2 and the first of the round bilge F12's are done this way also. The whole boat can be laid up with just 3 widths of foam thats coved on the 4 edges and then just glued to get the 3D shape. I have yet to see an easier method than this Cheers RG  Description: Construction Steps

So, in one way we went into the F12 concept the wrong way. We decided to go for a chained hull (wood) because it would be cheaper and easier to build. At least for my part I have learned something. Even if we keep the original idea of the kids participating in the building the foam/glass construction is easier. At least the foam stripping, that’s like making a jig saw puzzle. At least its a fun jigsaw puzzle.....and it will keep on producing fun :-)

Oh good, it looked like there was carbon against the aluminium beams, which wouldn't be good.

We like the look of the hardchine hull and chose this form over the round version, the foam should be more durable, also people can use our frames to build in ply if needed. The time it's taken us has nothing to do with the build method; lots of other distractions, the flat panel construction is a simple, low-risk option.

What I'm finding (which is not a surprise) is that everyone wants an off the shelf product and ideally an established fleet. No doubt about that. But then again, it just takes one person to build a class (if it is the right person). Most people are followers.

"A fleet" comprises how many? (estimated)
By plastic version, do you mean rotomolded?

yes rotomoulded. Still discussing numbers. It will depend a little on how many we can fit on their trailer broken down. Interesting that viability for potential rotomolded (larger scale) production in this case is associated to larger volume hulls, ease of transportation and simplified rigging - not outright speed. The last 1% speed is irrelevant provided that it sells and helps keep the numbers growing. Congratulations!

From the LR2 pictures it looks like the boat should sail in its longest waterline, not with the bow up atitude seen in the photos.
It might have happened due to the kid's lack of experience or because the tiller extension was too short, but perhaps the rear beam could be displaced forward to force them to seat in the right place? Or maybe that will be a problem downwind?

Once the kids sit in the right position, Im sure the bow will sit in a bit further, probably doesn't help that Billy's son is 12 kg below what it was designed for either. If I have to change anything it will be to add a bit of volume aft but Im loath to do that as I wanted the boat to be largely pitchpole proof so we don't scare the kids while they are still learning.
We will learn more this weekend when they are out again and hopefully we will see a bit more breeze so that they can push the boats a bit harder.

I don't think you have to change anything. It's absolutely the same thing on both the Tabby and the DS 12, where you put the weight is of great importance and it takes a good part of skill to make the cat go fast. So may the best sailor, not the best boat win the race. Have since found out that Bill's son is only 36kg, so its no wonder its riding high. On the plus side even though there was little wind this past weekend, we found out that a 36kg kid can right the boat by themselves which is always good :-) Hopefully the forecast 15-20 knots for this coming weekend will arrive and we can have some fun pushing the boats a bit :-)

Is that still a 7m^2 sail? It looks too big compared to the pic's of Gato's (or is Gato's too small?). Maybe it's just my eyes!

yup...7m^2 and max luff length, foot is smaller than on boomed boats as the sheeting line goes from the circular traveller (fwd of rear beam) to the head to be able to maintain foot tension. That coupled with a slightly bigger head makes it look bigger than it is.

If you could get a roto molded hulled boat at minimum weight to set up large fleets would they a peel to every one or just training academy's. is this good for the class as a whole, what do you people think?

Wow! looks cool :-) but I'm interested in relatively simple design - which I could build myself, vudu is not so simple as plywood boats but from other side - no nanotech involved.
Is there any chance to get vudu plans?

Vudu wasn't a playwood boat, it was E-Glass/Foam construction, the new one will be strip planked foam with E-Glass, quite possibly easier/quicker to build than the Vudu

Sure, I know that the Vudu is e-glass/foam boat.
Is there any additional info about your new e-glass/strip planked foam design?

Build method will be the same as the LR4 and the design displacement has been bumped to 115kg. Other than that, the rig and appendages are the same as the Vudu.
