Putting together some numbers on cold-mould material. Surface of hull is 9.93E6 mm^2. Will need 7.4 sheets of 4'x8'x3mm BS1088 marine ply. Assuming 10% loss but have 2/3 sheet to make mistakes.
A change is looking up for frames made from ply sheets as well instead of oak. Cost by BF is very high but efficiency seems to make it about even overall. It appears the length of the curves from shear to shear (is that gunall to gunall?) is nearly 2 meter for stations 7, 6, 5, 4. For a first design of a laminated frame built up from 3mm plys it requires 1/3 of a 4'x8' sheet. Considering 3-5 frames in the station 4-7 region focused about the centroid of the keel 2 more sheets are needed.
There is very little design ready for the internal structures, bulkhead etc. Looking at 6mm sheets there and maybe another 3mm to build 9mm if needed. So....1x 6mm, 11x 3mm. How's the glue holdin' up?

Hi! I've been following your build for a while and this is really good work! I'm an amateur builder myself, having built a Mirror and a Vagabond before. Might I ask where I can get plans for the F-15? I've been having trouble locating said plans. Cheers!
Hi Francis, thanks for the comment. If you go to the Uffa Fox website http://www.uffafox.com/ you can search through all the plans that are available. The plan was useful for the full size keel and rudder plan but the loft table is all you will need. The plans do not have any detail on construction.
The guys who cast my keel are in California and they still have the plug if you need one or depending on where you are it is cheaper from England.

Hoping to pick up speed soon but marine ply is not in hand yet. Dont hesitate to comment, thanks.
