Well, Vaea is back in the water, but I'm not sailing yet :( There was some rot in the upper portion of the mast, near the blind sheave. Vaea's mast is somewhat of a hybrid: the upper 3' and the first 5' are wooden according to plan. The central portion is aluminum: this is how it came to me.
The lower wooden part is still in good shape, and eventually I will replace it with aluminum, but I want to go sailing this summer :!: :!: But I did order some 1/8" x 5" tube to do the top. Here's a shot of the mast at the left (looks bigger due to being closer to the camera), the sleeve (with the "serrations") and the mast top:
The "serrations" are to prevent any stress in the outer tubes that the edge of the sleeve could produce. I doubt that the wingsail rig would actually stress the mast that much, but it only took 30-45 minutes with my angle grinder and a metal-cutting wheel. I cut the holes for the crane and the jib halyard box today, so all that is left is to drill the lower mast, set the halyard exit plate, and fish the jib halyard up the mast. When will it ever end? :lol:
