Another point that seems a little lost in the boat description...the ama's have what seem to be lifting foils forward of the front beam....kinda like the Catri concept...the boat also has a dagger board in the main hull. Rudders hang off the ama's (unlike farrier & catri designs).

Mike.

I suppose lifting foils are becoming 'standard' on racing tris, as opposed to the self-righting mechanism. The geek factor here is very high, so no wonder the focus went there.

It would be surprising if this boat was designed to be sailed on two hulls, like the F-boats. Hence the rudders on the amas. Central daggerboard as a safety aspect I guess. Technology looks pretty much like a scaled down ORMA60.

Those come standard with seat belts!? Wooo-hooo!

It's a very wide boat, do you want to be strapped to the seat when the [noodle] hits the fan? <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

No kidding. Did you see the video? Look at how seldom the bows ever go in! Seems to be "on plane" most of the time.

The strikerless design with curved crossbars gives a nice hollow underbelly.

I would like to believe it as well, but unfortunately the photo does not indicate that we can.

If they somehow tested the self righting system, it is reasonable to supose that the photos would be posted in the website, so we can reasonably assume that they haven't.

Unless there are engines hidden inside the beam locking system, I see no means to fold the amas and self right.

The giant pins locking the beams in place seem quite difficult to remove. I can't see how they would self-release in the event of a capsize.

Until the engineering problems are solved and the boat is capable to self-right, we can only believe in what we see: a nice folding tri that requires lots of R&D to become a self-righting vessel.

yes, but the lack of bows is what has me turned off from the design. Eventually, they WILL go under <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

Pehaps the lifting foils will counteract this tendency - looking at the photos the boat has enough volume in the amas to support the whole boat without the lifting foils. Having seen some footage of tri`s with these slanted lifting foils, all I have to ask is "why ain`t I got those on my boat ?"
I watched some promotional video footage of the Seacart 30, and when flying two hulls the boat pitches quite a lot in gusts, even in flat water - I`d think that they missed the opportunity to counteract this using lifting foils, and would hate to see how much pitching happens in a lumpy sea.
Anyone have any ideas as to why it would be a bad idea to implement these type of foils on a small beach catamaran design, I`m listening...

Hmmm. Call me stupid, but in the photos I can`t make out slots in the hulls for these "lifting foils", and they don`t seem to be a built-in component of the hull either. - did they not make it to the production phase, I wonder ?

Steve,

I was talking about the bows on the exploder 20 cat that was pictured on their site.

They were present during building at least..



Luiz have some good points. I am waiting eagerly for more news about this project and especially the self righting technique.

23 feet wide and 23 feet long.. I seriously hope they get a class going based on this. Would be seriously cool and attractive boats. But I would want Phill Brander to design mine <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />

They attend a few big regattas here in Holland and always do very well, if not better, than Tornados, Nacra20s, M20s and other Supercats (TR <=100).

Thats nice.

I don't recall saying anywhere that it wasn't fast.

The description about the righting system states that the arms each have one "quick release pin" that needs to be pulled before folding. I can't imagine a pin with shear load on it (weight and or buoyancy, and possibly rig tension) to be less than extrememly difficult to extract.

I'm pretty sure I see the slot for that board just between the "n" and "s". I really like the concept behind this boat - but I wonder how difficult those boards are to work with when they are so low on the outside of the hull like that. I'm willing to be they have some ingenious line to control that board.

Whats with the mobile home sponsor? Doesn't seem like good marketing <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
Although the DUO 1100 looks interesting... <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />

I think the same company makes both the boat and the mobile homes.

Jake lets go halvsies on one of these bad boys.

Sorry there, I didn`t notice this thread had migrated into a discussion of two different boats, thought we were all discussing the tri.. Perhaps I should read the header of each post more often.
On the flip side, if you`re worried about the bows going in on the cat, maybe you could just ask them to add the lifting foils ? Or am I the only one who thinks this might be a feasible thing to do on a beach cat ?

Well spotted Jake - I was looking much higher on the hull side, above the name. Didn`t expect them to be so low. Would you need to pull them up and down while sailing, or would you just put them down and leave them there for sailing, only pulling them up for beaching ?

I have no idea - my concern would be getting a big bugger on one during an Atlantic Crossing while it's blowing 30 and having to clear it.
