Ho ti all! I'm a new owner of and albin vega from 1972.
For the mast compressione problem I change the bulkhead with new ones in certified plywood I'm going ti installa It but It serms that the beam must be pushed up 0.5 mm (with a jack) against the cieling "with force" (100kg c.a.)to reach the correct hight to install the "posts". It Is correct?
Thankyou in Advance, best regards.
