Kiwi F12 Build Pics

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 shot of the jig

Cutting the foam cores using templates

Cores joined together

Peel Ply and 1 layer of e-glass on melamine board (waxed)

wet out of first ply

Another ply added and resin applied

Roll up the 2nd ply

Place the cores on the 1st ply

roll out the 2nd ply

Add another layer of peel ply

Breather layer added, plastic sheet over the top, vacuum lines inserted (one either end), all edges sealed.

Vacuum turned on and and then you wait till its cured.

Will post more as the job progresses.

Cheers
RG

facinating!

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

Hope you have a really flat floor with no humps or bumps...

Regards,
Bob

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

Dry Fitting the panels....note the slits in the bottom panel....more on this later

Dry Fitting the bow

Be sure to tape the frames before you create a bog cove for the panel tapes, makes sure it comes out of the jig.

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.

Looks like you are doing the Kelsall KISS procedure. Seems like a great way to do a set of foam/fiber hulls fast!

Very interesting. I had never heard of the guy, yet he lives just 30 minutes up the road from my parents.

http://www.kelsall.com/methods.html

Kelsall is one of the big ones in larger multihull designs. Been at it for a long time!

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

All the cores for the other 3 boats.

How are things going? What are the latest on buying the plans?

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

William

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

I like very much.

william

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?

As soon as I get out of the mess with all the different buildingprojects on hand for the moment, I will give this one a try.

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....

Regards,
Bob

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.

Here's a photo of one hull being held together.

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.

Cheers
RG

Well, I guess that the last post outrules the boat for me, it will be too expensive to get the things here...

RG,
If possible, I would also like to have the plans.
Thanks!

Gato, boards etc can be made and plans are included if you wish to make them yourself
cheers
RG

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

That is very clever!

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.

Regards,
Bob

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

As Chris stated. 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="" />

Mono-slugs are the dark side...When one steps up to cat sailing then they have entered the light...

Regards,
Bob

Bob, I totally agree.

It is all part of a conspiracy designed by what will ultimatly become the Universal World Power. I think George B. is behind the naming of the boats....

That's the democrats' version. The republicans blame Al Qaeda.
Wait! Oh, no! George B. and Al Qaeda are conspiring together <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />

That's incredible, nice work! <img src="http://www.catsailor.com/forums/images/graemlins/cool.gif" alt="" />

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.

"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…?

Regards,
Robert

And the last thing anyone would like to deal with at sea is a Tornado.

On the other hand, falling from the border of our flat earth directly to hell would be even worse...

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="" />

How's the vudu going?
Very keen to see any progress
Cheers

in about april someone said

"Vudu 3.8 and we'll have a website up sometime soon at vuducats.com"

doesn't appear to be anything yet

hope it's still coming, such a cool looking boat

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.

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

so should I try and get one set of beams anodised pink then?

ALSO, Karver put out the KB6 block in PINK !!! Kids can't hit the water without matching gear !

http://www.karver-system.com/site/us_news.php

scroll down to see the pink KB6 <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />

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

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.

How about "no bow rubbers" and "wear helmets like Kayakers ?"

Seems to be the cheaper and more easily implemented solution for this situation

Wouter

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.

What do you think?

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.

Any measures beyond that are up to the owners.

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.

Jeff, just for you :-)
enjoy
RG

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

I think these are going to be stunning boats RG. Good job.

I second that.
RG and Scarecrow being that you've chosen boats from different materials I'm very interested to know what paints, sealers, undercoats you recommend and why.
regards

Jeff,

For sealing timber structures I always recommend multiple coats of Evidure applied as per the product data sheet.

Resins and composites I use and recommend SP systems (Gurit)

Silicone adhesives and sealants Sika-flex

Paints I use Jotun or International.

saw this link to the multihulls article on boatdesign.net
Vudu Article

Its a great article, thankyou Julie if you read this, I'll try and follow up with a DS12 one to get some momentum up in that publication.

That's a great article indeed. well done !

Picture of hull 5 going together
http://www.catsailor.com/bb_files/153102-joiningwebpic.jpg

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.

sorry that pic didnot work trying again(not as good as gato but sill coming along)

beam landings

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?

About the beams>>> 1) What is the diameter? 2)Wall thickness? 3) Alloy?
4)Radius of the bend?

Regards,
Bob

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

Luiz, I think you can be right, the activity on my blog has increased quite a lot also.

GREAT!

How far are we... any of the cats in the water??

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

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.

Cheers
RG

and yet more pics

and the last lot of pics

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

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

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?

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.

Indeed. I did not look close enough, maybe just wanting to see more...

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.

Lookin' good!

One question though, are they carbon or glass beam sockets?

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

Yes, socket tubes are E-Glass and epoxy, but have carbon tabs/reinforcing to hold them in place and spread the loads

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 :-)

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.
cheers Bill

Did it come true

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.

It seems to be the same on the F14 forum. Still I'm thinking of building one

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.

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.

Interesting comments Rolf.

I think you'll find that I'm in complete agreement here !

Wouter

Where is the problem? There is a class with good rules, I have two boats complying, and sailing so just get yoursef here to follow

Hi all just to let you all know we will be launching 3 vudu's on the 28th feb to expand the interest will post photos then. long time coming and all but thats life
cheers bill

Great news, there are things happening in Finland also; http://www.aijaa.com/v.php?i=5632309.jpg
It's not me this time, and we will maybe run the first competitions next summer

Thanks for the good knews! Glad to know that things are moving. Slow progress is ok, provided there is progress.

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).

"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!

True, although as I mentioned before they don't know about the simplified rigging. That's me trying to cut costs.

Good news.

well we have launched vudu 001 hc and what an awesome cat it is very quick responsive the kids loved it and so did the big kids tacked easily had an estimated 15-16 knot blast bow up the whole time through waves and all awesome and so much more to come will get more pics to post
cheers bill

That looks awesome, finally an alternative. Now the Tinaroo kids don't have to go from a bic to a laser!!! Love your work mate!!

Looks good! Great news!

Thanks RG, how long did it take to rig each disassembled boat?

About 30 min, 10 min if the hulls are assembled
cheers
R

Fantastic looking boats Mr Geek! the kids who get to sail them are very lucky indeed!

Long have we waited but not in wain, they looks great.
Weight of the cat, is the 50kg min weight more or less all right?

We haven't weighed them yet, but Billy thinks they are slightly under weight by a few kilo's

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.

Great news! It will certainly float on its design waterline with the right weight, more breeze and correct seating.

Luiz

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 :-)

Good luck, the F12 is not a problem even for a kid in +15 knots. Some other cats can get difficult even for adults in +15 knots...

here's a few more pics

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.

for anyone interested, just found this on Trademe
Vudu - F12

Interesting..I read the whole thread .

Hay guys theres a sail world post about these boats.

http://www.sail-world.com/NZ/Junior-Training-for-the-Americas-Cup/83589

Great article!

looking forward to seeing fleets of these

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.

Hi all, how can I get vudu f12 building plans?

micklev, we aren't doing the Vudu any more as we are coming out with an updated design in a short while based on the pics here

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.

Thank R.R, please keep all community informed
