The varnish finally cooperated. I’ve been working on another project, but first, a story.
In January, I took this boat to Florida for some winter cruising. The first time I ever rigged and launched her was on a lake in central Florida, solo. I had a nice first sail. I beached her near the ramp at the end of the day. I took the locking nut out of the main tabernacle. Slowly but firmly, the mast lowered itself while I was lying on the deck. It pinned me like a wrestler. I lay there, arms and legs flailing, calling for help. I was helpless! A fellow boater came to my rescue. Something needed to be done.
I’ve been working on a solution ever since. Graham sent me his solution, which required 3D printing or machining. I needed something simpler. It took three design iterations (actually three and a half), but I now have something that actually works.
I wanted something I could deploy from the cabin top. To activate it, I hook the ring on the top of the bungee onto the screw. The latch has plenty of strength for holding the mast upright, while I reach down to attach the bolt at the aft end of the tabernacle.
This is a closeup of the working end. I have a couple of links of chain at the bottom, so the tension can be adjusted when necessary. You might notice that there’s a section of angle aluminum on the underside. This stiffened it up, eliminating some pesky flexing.
To release it, I simply flick the ring off the screw.
