Radikal T26 trimaran by Perspective design

Radikal 26

Theres a thread here* that has some figures for the angle of heel of a tri when it's just flying the main hull-will be interesting to compare this with those. When you have a narrow overall tri with a main hull that has a lot of rocker the likelyhood is a high number like 17-20 degrees+. The only one, besides my model, that I always remember is USA 17 at 13 degrees.
A boat that heels less will be faster unless the boat that heels more has a canting rig.....

The Radikal T26 has been out on it's first test sail in light conditions. There is a short video on their facebook page:

Damn good looking boat! Still have reservations about the beam-we'll see.

 

Nice looking new boat

I am not trying to second guess their design, just interested in details. My Buc 24 is 19' wide but carries its floats a little higher ,and I have thought it might be better with even more beam. I wonder how the 26 will work in bigger waves with the seemingly fine entry of the floats. The boards seem quite large from my experience, are they assymetric?
Also, are there any upper control arms for folding control, and can it be folded in the water?

The fine float bows are supposed to work in conjunction with the lifting foils to keep them from immersing too far. I haven't seen any evidence of an upper control arm so I assume it's a fold on the trailer boat. I'm looking forward to seeing some sailing in stronger conditions too.

 

A new video shows the Radikal T26 in a bit more wind, looking good so far:

Looks good! I'm thinking that they'll have a large angle of heel if they fly the main hull?

 

Their latest video, nice speed and stability for a 26' trimaran. I'd cant the rig if the angle of heel was depowering the platform excessively it's pretty easy to do on small boats with light gear.

wind speed

I don't see many whitecaps, so I assume the wind is under 13 knots or so, and the leeward float looks as if it is almost ready to bury- and they are not close hauled. Am I missing something, or maybe it doesn't matter with the wave piercing floats?
Pretty boat though, and floats are easy to change

Phil Roulin mentioned the other day on FB that the Exocet 19 trimaran is being manufactured in Marseille.

Exocet 19 with UptiP foils

Thats great news Corley! Can't wait to see it sail/fly.....

 

Phil Roulin at Perspective Yacht Design has put up a picture of the CNC machined float hull plugs for the Exocet Extrem 19

 

Raked stems--o.k.
Rocker in the aft- sektion--o.k.
But the ' caves " in the sides ?
Please, tell me why.

Caves in the sides;
Well those ridges are going to provide a bit of stiffness to the panel, maybe he is revisiting Dick Newicks "half moon" idea that the concave shape provides lift as it is depressed ?
