This is great! I'm a big fan of Chris Morejohn's designs, looking forward to more updates!

Great, Frederik!
This hull shape will make the best use of the plywood. I never understood the idea of buying those wide sheets of plywood, and then slicing them up in narrow strips, AND THEN glue them back together to emulate round-bottom lapstrake designs.
Single chine or double chine makes most sense to me when building in plywood, aluminium or steel.

Good luck!

Scantlings mizzen mast. 

I have bought the CF mast recently for sale here at JRA. I’ll be using the top 44 ft and the specs look good for that section.  So that problem is solved.

As for the mizzen mast.. I’m not quite sure as how to calculate the specs for that one. 

5,5 - 6 meters total length  carrying  a small 9 sqm sail. 

I’m thinking of calculating strength based on sail area. 

9sqmx 7,5 kg/sqm  wind force = 67,5

3 meters up the mast. 202,5

safety factor 3 = 606 say 650 kNm

I’m thinking of an alu pole of 120 mm diameter at partners tapering to 70 mm. Wall thickness 3 mm

Anyone want to chime in..?
