Thanks Phill,

I think I have a few more issues solved now. I'll mail you later. The trick is indeed in planing the corner ceder rods to the right planes. I'm thinking to have the prototype made using stitch and glue and then use the sides of this single hull to plane (route) the ceder to the right angles allowing the other hulls to be build much faster. This will really kick in when a group is building multiple boats.

It also means I can look again at the multichine wave-piercer hull design ! And I really want that because it can be made to look really good.

Additionally the chines themselves (especially the one on the side panel) will make the hulls really resistant to hitting things as all V-ed shapes are.

It is looking good.

Can you give some feel of how much a F12 hull will cost in material (using the 5 panel multichine hullshape using shaped chine rods).

A rough guess at this time will do.
