You can see the two crossbeam attachment points and the shroud attachment point between them. Another set of photos show the two halves being bonded together. Now on to the other float hull.

This is getting HOT!

How was the float shell joining?
Any problems?
And whats the weight of this first float as it is right now?

I still think, you are a bit overdone with the internal reinforcements.
They surely can be reduced a lot for the carbon boat -
and that will create the final weight difference between glass and carbon version.

But your built surely looks awesome!

Status: offline 		Here is the first "completed" float hull with nose and transom added. The completed weight is 1 lb or 454 g. It will go up ever so slightly as I fill and finish the seam. There were no real problems in bonding the two halves and the bond was very good and strong. There was a little distortion in the overall deck line due to the internals slightly misaligned but that was easily straightened out with a heat gun and a little manual manipulation and reforming. I am very surprised at how strong the overall assembly is and as I already stated the internals are very overdesigned. I will certainly be modifying them when I move on to the carbon version. The bare carbon fiber halves currently weigh in at 12.5 oz or 354 g so when I add the modified internals it should be even lighter then the glass version. The bare glass hulls were 12.85 oz or 364 g before the internals were added. These float hulls are lighter then my existing float hulls on my Snapdragon mini 40 tri and have more overall volume as well. They should be really good performers on the water. Well on now to complete the remaining float hull the same as the first.

Status: offline 		1967250s,

Idealist asked me that same question. I think he was working with a connection in China to potentially kit out this design (see the Trimaran Plans forum). For me it is a wonderful pastime and hobby and I enjoy working with the different materials and experimenting with different designs. I actually sat down once to add up what I spent in materials to complete one of these beasts and with using top-notch fittings (most Sails Etc), custom sails by Carr sails, radio & winch, exotic materials like carbon fiber and high strength epoxy and it came out in excess of $800 US. Pretty expensive hobby eh. That doesn't include the many hours of labour. I did make male plugs for all the hulls so that I could make two identical boats using different materials and internals - one as the basic robust design and the other to maximize strength and minimize weight (ie a race version). I don't belong to any model yachting club but I am thinking of possibly joining one this season. There is a very large club operating in my city. - Metro Marine Modelers. I don't believe that they have any tri's in the club but who knows maybe I can get something started and put those hull plugs to good use. I the meantime I still have a lot of building to finish and I'm racing to get this done before my local pond gets unfrozen and the sailing season begins.

The only thing I got back from that "China-Connection" was a single 3-D drawing of the mainhull -
based on the free plans I sent to him - together with a WORM/SPYWARE to spy out my PC!!!
Some people are simply UNTRUSTWORTHY!

I´m allways willing to share my knowledge and experience,
but if I´m tricked then for doing so I really get mad.

And allthough it has been proofen for not working properly,
some UK based persons are still promoting the GHOSTTRAIN:

Sorry to hear about that bad experience. However on a positive note with so many people now being issued your plans it is likely that you'll be able to see the Nightmare tri being built and sailed in many countries in the world. That is a testament in the fidelity of your design efforts in this regard. Keep up the good work, as I believe that you are on the leading edge of the design concepts. I'm really anxious to get my first boat completed and out on the water. My excitment is building now as more and more of the boat is getting finished.

Well - it actually didn`t cause any physical damage - just disappointing me. -
It makes me kind of sad to see people like that, who think it´s necessary to trick other people at all.

Umut Korkmaz from Istanbul/Turkey is the 100 % positive counterpart to that Engishman who works at Hongkong!

Australia is "surrounded" by my designs/plans for example - Queensland, Perth and Sydney for sure! *ggg*

Status: offline 		I have essentially completed the main hull now joining both halves and adding the nose piece and some custom covers for the servos access. They were made by laying up some 4 oz cloth over the hull plug in the area of the cutout, so the fit is the exact shape as the hull. On on my other tri I covered these accesses with Monokote film, since they are rarely ever opened but decided to try some covers this time around. I have included some photos of the main hull and float hull up against my existing Snapodragon hulls so you can see the differences in the shape, volume and rocker. The float hulls are not that much different but the main hulls are quite different, with a huge difference in volume. The interesting thing however is that the new main hull only weighs 1 oz more than the existing one, despite it's larger size. I expect that the carbon fiber version will actually weigh less than the existing one by several ozs. I've just got to bond the remaining float halves together and essentially the hulls are complete and I will focus my efforts on making a set of moulds for the crossbeams.

Status: offline 		As outstanding as usual (for you), TBK!

As the hulls are basically still pipes it should be clear, that a pipe with a bigger diameter can have less wall thickness and therefore equal or even less weight than a thinner pipe.

When I designed this Mk.VII - I allways kept in mind that it is actually a 1:5 model of a 20ft. beachtrimaran -
instead of a 1:10 model of a 40 ft. offshore-racing-trimaran.
For a 40ft. Trimaran you of course would add a cabin as well - and these identical hull proportions would fit for a
long-time-cruiser-trimaran.
A model like this on a lake - in relation to wavesize - will allways be/sail like an offshore boat.
Therefore less hullsize or less bowheight are not only useless, but counterproductive.

I´m looking forward to see how you design/build the crossbars -
and it even could be time allready to think about a nice paintingshema!

You´ll be the hero on your pond, when you show up with that outstanding boat(s)!
But be careful - ENVY is the next thing you got to deal with then -...- *ggg*

Already got a paint scheme in mind. Since all my current boats have been black & white I thought that this time I would go with red, white and gray. Attached is a photo of the Brossard offshore tri that I was considering (less the advertising/name and the model wakeboarder) as a possible paint scheme. It would have sails with matching red reinforcing patches.

And that´s my favourite!
Allthough the size/scale doesn´t fit at all - to say the least - as this beautiful beast is 40 meters long!
Please note on picture 2 that the whole rigg is inclined to windward,
which is done by huge hydraulic pumps placed inside each float.

Status: offline 		No not speechless, just a little busy. I do like the "Banque Populaire" design as well. Since I'm building two boats one will be red & white and the other will be blue & white. I have ordered my sails to match, one with red reinforcing patches and the other with blue. I've finished all the hulls for the first boat and I'm starting on the molds for the crossbeams tonight. They will be similar to the ones I used on my Snapdragon tri with a "D" shaped profile. I'll put on some details/photos as I work through it.

I reckon you should make a wake boarder or two to drag around! What a hoot! What a video that would be. Cruising past a marblehead at speed with wild wakeboarder bouncing over wavelets. YOU CAN DO IT!

The workmanship is first class and the sails perform very well. He can usually get them to you within a couple of weeks of placing an order. He is located in Redmond, WA. USA

If you type in Brossard Trimaran on the web search you can find a number of videos (on You Tube) showing the boat towing two wakeboarders. It's way cool. I towed a wakeboarder behind my 20' Tornado catamaran on a howling day way back when. Unfortunately I never got any video and I have long since sold that boat.

Status: offline 		Hi TBK,

I thought I would reply to your inquiry as to my Nightmare build from the Foil thread here. I am doing a somewhat different building sequence, I intend to finish all the exterior hull and float pieces first before proceeding with the interior framing etc. I may have misled you with my poor choice of wording in saying I have finished the Main hull, actually as it stands currently, only the outside shells are somewhat finished.

I used 1/8" balsa, with plain 2.5 ounce E-glass, utilizing US Composite Epoxy. So my build is decidedly low tech/low budget and mundane in comparison. I have no doubt that your use of S-glass is better and the Carbon Fiber is the best route to go. If this being my first Multi-Hull construction I took this as a learning experience and will use the more advanced materials in my second build of a Trimaran, hopefully a 2 Meter.

Although it is somewhat down the road in the construction process, I have given some thought as to how I might go about building the float arms. I thought of utilizing some multiply 1/8" Baltic Birch to make a vertical spline pattern of the full length of each arm and in turn use this as a template to cut out matching shapes from the pink or blue insulating construction foam. After gluing the foam to both sides of the plywood spline, it would be relatively easy to sand the foam to an aerodynamic and eye pleasing contour. Covering the arms in fiber cloth or better yet, Carbon cloth, this is where I would like to try vacuum bagging for the first time.

As for how to attach the arms to the floats? I toyed with the idea of perhaps having a carbon tube coming out of each arms end, which would mate to the inside diameter of another tube installed in the float. A lock pin, of aluiminum or maybe solid carbon rod would hold it in place. Another way is a threaded insert in the float itself. I am kind of leaning to simply gluing/epoxying the arms in place. Not exactly conductive to portability or ease of transporting but my R/C boat transportation to the local pond is a Pick-up, so that would not be much of an issue with me.

As soon you are done with the Mini40 Trimaran, you can get plans for a 2 meter Trimaran as well!

http://members.chello.nl/~t.iwema/2MTri.html
But to give you a first idea - this link shows some of the drawings I made for my "Bonduelle" in 2003.
The first full carbon/epoxy 2M-Tri at Austria.

-...- and once again, there was this man who got the plans for free -
but forgot to mention my name as the designer on his homepage-...-
-...- some people are not worth it -...-

But here is the link to my galleries, where you can see the completed boat:
http://community.webshots.com/user/boatbuilder

Plus an overall view of the "FONCIA" and the plugs I made in 2007.

Thank You Kindly for the glimpse of your designs, both Mini 40's and the Two Meter Trimarans. The look see is certainly an added incentive to accelerate the current building project. I have enjoyed the process so far, while at the same time realize it is just the start of a long learning curve to a different facet of R/C Sailing, Multi-Hulls. I am especially looking forward to the challenge of sailing these craft, trying to keep them right side up while going faster! Certainly going to be a very different experience than sailing my Mono Hulls.

I am sure the many worldwide recipients of your Free Nightmare Plans (78 and counting ) appreciate your generosity in sharing your time and knowledge. In viewing your picture log,it is obvious your designs have evolved over many years. Years of significant experimentation, time, thought and effort.

Rest assured you will be given full and instant credit as being the designer of the Nightmare Trimaran I will be sailing. Hopefully both my building and sailing skills will do justice to your design.

Sailiing season is approximately six weeks away. Time to get back to the Sailboat Building Dungeon!
