    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.....

    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?

    Corley epoxy coated

    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.

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

    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 :)

    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 ?
