Re: Hi, we too got a new/used Cal 21

Rippy, the transverse bulkhead just forward of the keel well is VERY necessary! The forces of the keel act against that bulkhead reducing flex of the keel well which prevents fatigue at the point where hull and keel well come together. Secound, the forces of the mast pushing down and windward shrouds pulling up and in are resisted by that bulkhead. The whole midships countertop that serves as a cover over the head compartment and (on our boat) the galley to port, is actually a box structure that distributes the whole stresses of the athwartships (across the boat) forces of the rig. You could elimiate what is there, but only if you build in a substitute structure to take it's place. Even with all htat structure we had a crack develop at the forward end of the keel trunk where it meets the hull, as the keel moved slightly underway, the crack would open slightly (1/8" or so) and water would squirt in. Had to haul boat our and glass over the crack inside and out. That is also another reason to keep the pivot bolt at least snug while sailing, in addition to using the keel locking bolt.
