We have just gotten back from our tour of the east coast and Bahamas so it has been a long time. I noticed that you have an issue with the shaft tunnel. Your "drip" will be found to be water actually entering the lamanate and working it's way up around the massive bronze housing that is the shaft tunnel and packing gland. This is common on Nan Tais and there is a solution.
You need to pull the shaft (easier said that done) and then using an angle grinder you remove the glass covering the packing gland.

Good Morning. I am about to purchase a Nantai 37 in the Turks named Xanadu. Do you think this is your old boat? Anything I should know? how did she sail with the in mast furling? thanks so much, Ed
