I'm a little involved in polyethyleen kayaks and these weight about 22 kg for 3.55 mtr length. The volume is not unlike a small cat hull and so it appears that 25 kg per F12 hull in well redevelopped PE (poly-ethyleen) is possible. Pretty much putting the ready to sail F12 at about 70 kg.
25 kg per hull. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />
My F16 hulls are lighter than that. I admit they have some pretty fancy work in them but surely and F12 can be lighter than that. The Arafura Cadet have a minimum platform weight of 36kg and that design is 45 years old.
Who is going to carry this 70 kg beast? I still remember how heavy my near minimum weight AC was.
