Still preparing the lower port hull surface for glassing on saturday!
JWD advises to cut 100 x 25 mm depressions, 6 mm deep into the skeg for rudder lashings before glassing. We will to this after glassing and therefore we made a test-sample from 12mm ply + 4 layers of glass and fillercoat. Then we cutted the depressions with a router and a " copydisc". The result you can see on the photos.
