-...and also how do you get in and out? You won't be able to stand on the 'wings' or the nose cos the thing will roll/pitch/sink like a bitch.

i'm getting behind on building this, even answering here, sorry guy's! excuse is we had our sundancer back from france and it eats -a lot of- time and money too.

got the 3 (bigger) legs ready, the arelons (that'l be the fun part), even the poles in top of the rear legs who are intended as grips to board couse the thing will heel but the volume of a fully submerged leg carry's about a 100 kg. yes it needs a extra long tail OB. the pagenger sits in the middle (still to make) and wont shift weight, total should just submerge more. i want to, but havent tested a single leg yet. should be getting the alu triangle and more. i still belive it can work and may be fun.

i'll post the stability graphs and pic's asap.

Hello Yipster!

why not try to put down the outboard engine in the front of the bow.

As the hull pushes the water forward to the wave of bow you maybe gaining som of power to pressing the wave backwards and also reduces the volume in the wave. Also you do put the propeller in the forward stream of the bow wave. It is this wave the dolfins ride on. maybe you still have some turbulent on the propeller.



Hehe totally brainstorm, I know but I love to let my mind "float" away.



Nope I havent smoke anything. hihi!

This is simply the way I am!
