    How much internal framing is needed to keep the shape of a strip planked hull? I need to get the outside glassed before cool weather arrives.

    I will add the stringers and floors (9 mm plywood). If I add a keelson then I can not lay glass across the center joint.

    The photos show the bulkheads with notches for the stringers. The hull half is laying on its side. This is a catamaran hull.


    Thanks for any comments

    Bump, maybe someone will have a good answer for you. Question tho, what is your reasoning for such a large number of stations? LOA?

    To add, I like your model. Very good design of shape I think. Have you filleted your bulkheads? From a purely amatuer POV I would believe that shape would be retained by the glass on the inside.

    Being an amature myself;

    I set the forms at 50 cm spacing because it made less of a chance that I would screw up when setting them. (dislexic sometimes)

    LOA is 14.5 meters. LWL 13.8 meters BWL (of one hull) 1 meter

    I have added 2 stringers. one at the DWL and one 20 cms up from the DWL. Figured that if I hit something floating this is where the loads will build up at. I wanted to add the keel and keelson before lifting it out. Decided it will be better to do that when the halves are already joined.

    No one with advice?
