Before I undertook anything related to the windvane removal, I tried to repair a disconnected cockpit scupper using the part I had ordered from Defender Marine Outfitters. I lucked out with guessing the correctly sized plastic elbow fitting for the 1.5-inch scupper drain, but I still couldn't get it to fit. Either the thread spacing is wrong or the drain threads are stripped, which would explain why the previous fitting was only glued in place. I expect that I will end up gluing the new one in place, but I'll wait on that until I'm ready to use up an entire tube of 3M 5200 marine adhesive on this and other applications, since the whole tube will start to set up as soon as it is exposed to air.
My greatest success has been with constructing teak frames for the cockpit cut-outs. I spent a good part of yesterday afternoon using a mitre saw to cut L-shaped molding pieces to fit, and then some time this morning gluing the pieces together. I will need to fasten some small screws as well, but the glue should hold for that process.
The molding was part of an order I placed through the West Marine website a couple of weeks ago. West Marine offers free shipping to their stores for in-person pickup, which worked even better for me than drop shipping to my folks' house. While I was at the store on Abercorn Street, I noticed that the Garmin GPSMAP 740s Chartplotter/Sounder was on sale for $400 below list price. I had to think about it for two days, but I couldn't pass up a deal like that on a necessary piece of equipment and went back to buy the last one in stock, along with an external antenna. The installation looks tricky, so I'll wait and have Thunderbolt Marine do it when I return in the spring.
Tomorrow, I'll see if the teak frames fit, take some measurements for some other projects, see if the engine will start and stay cool, and then prepare the boat to be left alone for another winter.
