Thanks Rolf, Thats something to strive for...but my calculations so far yield 25.5kg per hull... guess i have to thin the wood i will be using...myabe I will planedown the thickness at the bow and stern.
Carbons tubes are the ultimate!May I ask what weight of cloth you are using for the carbon beams and how many layers? I assume you are going to bolt a traveller track onto the beam..
