here is what i have created so far i like the look of it but i have a lot of fine tuning to get the hull shape correct
LCB will be between 56% and 58% and the LCB of the floats will be forward of the LCB of the main hull by around  300mm. the floats will be flat out planing hulls with wave piercing bows  and the main hull will be very round to reduce wetted surface area.
