Hello all, I'm planning on un-stepping the mast on my 1989 Beneteau Oceanis 350 to do some work on the masthead. Following are the considerations: Mast height (horizontal length of the spar) = 40 ft. Mast weight (excluding standing rigging) = 350 Lbs. I'm using total of 400 Lbs of weight in my plan. Boat is in a slip and must remain in the slip Not using a crane or other boats (no buddies) Mast is deck-stepped without a hinge at the boot The plan is to use an A-frame with block-and-tackle of sufficient strength to unstep and lower the mast. The mast will remain on the boat, supported at the bow, stern, and inbetween by appropriate structures. Questions: Has anyone lowered a mast in this way (using an A-frame) on a boat this size? Has anyone done #1 and the mast was not hinged? Does anyone have any advice, based on experience (not opinion), whether or not my plan is feasible and if it is, any tips to ensure success. Thank you all in advance.
