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.
WOW, excellent pictures RG...<img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" /> Kudos and big thanks for the posting...

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.
The slits in the bottom panel are so the panel can be curved into shape in the jig. After its in place and tabbed to the other panels, you fill the slits and glass over it. A grinder disk on edge was used to make the slits.
Thats it for now, with luck we will be able to show the finished half shells by next week sometime.
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.
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.
That is a very generous offer! Join the class club and get the plans..
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?
Great to see something actually being built instead of just talked about...but one question comes to mind that begs an answer: Wouldn't logic lead one to believe that building a single boat and testing it on the water would have been a better method of pursuing this?....rather than building four, without testing, that might share a common problem?
Never the less....Wishing much success with your project....
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

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.
For the record while the DS does stand for Dark Side (in my head anyway) it is a DS12 not a Dark Side 12.
Enjoy the exposure of a youngster to the "Dark Side" of sailing, without fanfare. Let the DS12, or any F12, be the enabler. <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

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.
"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."
A Tornado is a force of nature...Voodoo is a force in the supernatural realm. Hardly comparable in destructive power. One can destroy the body the other the soul.
Voodoo is not imaginary...it is very real...the Bible calls the demons behind such activities as "familiar spirits". One of satan’s greatest tools is getting people to believe he doesn't exist. You may or may not believe in God or Satan...but that doesn't change the fact that they exist...
Getting back to the boat names...One can see all the evil one can stand by turning on the nightly news...when a parent is looking for a boat for their innocent child, the last thing they should have to deal with is Voodoo. Again…the boats are great, the designs look sweet, the designers have done a good job…how about a better name?…any name without an evil connotation to it…?
BTW - another "one of satan’s greatest tools" is getting people to believe the earth is round. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

I'm sure its still coming. Its important to remember that the people behind the F12 designs are doing it for free and the boats are being home built by enthusiastic amateurs, as a result if life gets in the way every now and then it is to be expected.
Maybe the kids should vote for the names ? It's their boat right ? It should be cool for them not for the grown-ups.
If you don't like the names now wait till they start naming their boats. My daughters already got the big side stickers for DS 009 "Roxy foxy girls rule" definately not picked by me <img src="http://www.catsailor.com/forums/images/graemlins/confused.gif" alt="" /> regards

Oh you guys are great. I volunteer to be the F12 forum moderator so I can lock this thread before my kids see it <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />. 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
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,
Here's a suggestion for bow protector requirements:
a) Simple, inexpensive, effective, etc. - the usual. b) Universal - all F12s use the same, if possible. c) Big - for safety. d) Highly visible color (orange or red) - for visibility.
A standardized universal bow bumper serves to ID the novice fleet when racing.
Luiz, given that we have such different bow shapes and other designs will probably be different yet again, how do you think your going to come up with a standardized design ? 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.
given that we have such different bow shapes and other designs will probably be different yet again, how do you think your going to come up with a standardized design ?
RG,
You are right.
Trying to find a solution, maybe a compulsory sacrifice bow would do the trick.
An (easy to replace) sacrifice bow would be required of at least X mm length. Soft material painted red for novices; any other color / material for all others.
A soft bow could be a problem when beaching, though.
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.
The DS12 has a solid timber stem. While a little more complicated to build this was done to prevent the ply "splitting" in the event of a collision. Its not unbreakable but it is definitely more robust.
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. Cheers RG

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.
Update: see attached pics, 2 hulls closed up and ready for external tabbing, primer and paint. As shown with peel ply still on the outside, each hull weighs 7.7 kg. Expect the finished boat to be well below 50kg finished. Enjoy the pics Cheers RG

still moving forward all be it slowly here is the jig for setting up the beams(beams yet to turn up)and remember all things come right when you have a great class.
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.
Unfortunately no. we have two boats with beams on being faired for painting third having beams mounted but progress is slow with constant interruptions. bill
Chinese Vudu questions

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

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

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 :-)
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. cheers Bill
For a more rounded, softer hull design wouldn’t it make more sense… Instead of cutting the foam in narrow strips and routing all the edges with the subsequent loss of a considerable amount of material, why not just score through 70% of the thickness longitudinally.
Similar to what you did on some of the panels of the hard chine design but with much more precision… (in the raw foam, not foam that has already has been glassed) using a fence and narrow blade in a circular saw where you can regulate the exact depth and width of the cut rather than just free handing it with a 4" grinder. One could also make similar cuts on the horizontal plane at the bow where a compound curve is encountered.
It would seem to save a lot of time and material…that H 80 Divinicell isn’t cheap @ $100.00 US a sheet, and over the course of the boat you would end up with 2/3 rds-to a full 4’X 8’ sheet of foam on the floor in the form of dust.

I don't relly understand what you meen here. If you speek about the strip foam there was not a lotof loss in material. The Tabby was built from two sheets 1.2m by 2.4m 15mm thick. I ripped the strips with a bandsaw with a very thin blade. As the strips are only 5mm thick there was no routing of the edges. The total cost of foam (Airex) was about 150 USD.

Hi Gato I was referring to the build method they used for the LR2. Talking 4' X 8' plain Divinicell sheets and ripping it into strips and doing the cove routing method. H-80 Divinicell 3/8" thick, not Airex, and each sheet are $100 US at this point in time...and that is 1/2 of the list retail price. In regards to the quanities I quoted...I was using the amount of material needed to build my F-14 design..so if the waste figure seems a bit excessive that's why...
I would have taken this to the home building forum but there is not a lot of action there...not that the F-12 is a fire ball either.

There is plenty of interest, but few acually goes to the step of building a boat.
I am up to my ears in sawdust. Last night I pulled about a 1000 staples from an F16 hull panel. I would like to do a F12 but completing the three F16s have first priority.
What I'm finding (which is not a surprise) is that everyone wants an off the shelf product and ideally an established fleet. I've got all the bits here for a DS12 but as I'm working in excess of 70 hours a week at present and don't actually have a kid, it will be staying a pile of bits for a little longer yet.

The local sea scouts/cubs have just (last friday) placed an order for a fleet of the plastic version of the DS12 to be delivered ASAP. Freeboard will be increased to handle instructor + student but bottom will remain optimised for sailing one up. The other change is boats will have no boom (although the scouts don't know this yet).

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 absolutly 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 :-)
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?

Inexpensive boats at low cost will appeal to many sailors. IMHO More F12s is good news for the class, regardless the brand or make.
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
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.

Do you have an estimation of how many hours spent so far?
