Tabernacle Forces
Posted: Wed May 12, 2021 12:08 pm
So, i'm into the finish work now and hope to launch late June.
I plan to make my tabernacle removeable. I had already doubled the top of the interior of BH 2 and re-enforced the joint with double Tape on top of the overlapping glass.
But reading about some of the failures it does make sense that the foot of the sail will put significant forces on the tabernacle.
From a purely Mech-e standpoint, ideally you'd have mini-shrouds for the tabernacle pulling back against the forces exerted by the mast on it so they're not all transferred to the bolts / bulkhead. I don't see a way to do this as a practical matter. Particularly given the close proximity to the wide companionway. But I'm crazy enough to do it if I get a failure there.
I do expect to use turnbuckles on the shrouds so I can keep them tight, which i understand to be the first line of defense.
