On the plans for the Final Assembly of the Gypsy 28 Catamaran it was just staed:
"Set up hull so that CL are 4100 MM apart
Ensure hulls are parallel and that diagonal distances are equal
Brace well, Fit aft beam and knees
Join cockpit to Cuddy as shown
Cut Mast Beam holes in Cuddy
Glue and Glass cockpit to aft beam "
Haha.. it sound so simple but I have been spending a lot of time wondering how to execute this.
Probably it will take me the whole of this year to complete the assembly.....The items are heavy and I could no longer work alone most of the time.
