Now with masts alligned and installed.
I used spartite between the deck partners and masts, permanently attached to both, and weicon shore A85 as a wedge between mastfoot and the mast, attatched only to the mast.
It’s been a bit of a head scratch to get this part of the build right, with the different angles and all the lifting in and out of the boat, but it turned out fine.
The scariest part of the whole process was when the main would not readily slip the butyl tape that was underneath the flange of the partners.
but with patience and hobby knifing the whole lot came off.
Butyl tape may not glue, but it surely sticks…
