Finally did it...took about 2 hours actual time, though if you factor in all the staring and creative finagling, took all afternoon. But it was a gorgeous day here - perfect for readying one's boat for the water!!Thanks Glenn for all the detail and guidance!!See the Photo Forum for the details. (See link.)Primary goal was to add buoyancy at the top of the mast, and to make it watertight. Used noodles over expanding foam since I hope that to be easier to undo or repair if needed.I list possible advantages to the noodles in my posting.Can't wait to put the boat in! Maybe this week. Also added the Windex vane that I got for Christmas. And, quick release pins everywhere - hallelujah! New Boomkicker goes in at launch time. Only thing left is to rig the boom and mast hardware for reefing - that I can do after launching, though.Question...anyone have the Windex windvane survive a flip? When I go to do the test, I suppose I had better take that down!!Based on Glenn's success with his foaming, I am confident that this will work. Will post results once I have them!Sailing season has finally hit New England! (Frostbiters not included...;-)
