Hi Graham and Paul, first, my apologies for the late reply. My shed is nearing completion and my first project will be to make the tabernacle for, I hope, my junk rig mast. My thinking of a fibreglass tabernacle was that instead of a timber one, then sheathing it with Epoxy and cloth, I would make the whole thing out of vinyl ester resin, glass matt and woven roving to a substantial thickness. The finished tabernacle will extend from the boat keel to about one metre above deck level. In all about 2.3 metres. I have included a photo of my home built boat and of the shed. Best regards, Oz.
