Sunny. I left Boothbay Harbor at 0800 and once out of the inner harbor I raised all sails and turned off the engine. The wind was from the WNW at 10/15 knots. I sailed between the islands of Casco Bay to the Dolphin Marina, in Potts Harbor on the south tip of Harpswell Neck. I had never been here before but it was recommended as a friendly place with moorings and a great restaurant. When waiting for a mooring I noticed that the engine blower had stopped working. I use this blower not to pull air out of the engine compartment, but to blow cool air on the alternator, which otherwise has a tendency to overheat when at full output. Later I went ashore to pay my mooring fee and check out the restaurant. They told me it could get quite busy and to be early to ensure a seat at the bar, for which they did not take reservations. I went back on board to check out the blower, but could not find anything wrong without emptying lockers. Next time when I stay somewhere for a few days I'll empty out the cockpit lockers and check the wiring and voltage and maybe take it apart. For now I'll have to monitor the alternator temperature so that it doesn't overheat and blow the diodes. If necessary I'll adjust the regulator to put out no more than 90% of output. I went back ashore around 1715 for drinks and dinner. It was quite a big restaurant for such an isolated location and clearly it catered for a wider public than just transient boaters. At some point a helicopter landed on the front lawn and I was told that it was the state's governor coming in for dinner. I had a nice conversation with a couple on an old Alden ketch "Avatrice". I had seen this boat before on my Maine trips and the female captain told me that she uses it for sail training for women but that she now was going to retire after 23 years. Shortly after that I read an article about her in the September issue of Points East. On the way out I briefly spoke to a couple that had come in before me on a Kadey Krogen 44 ("Sea Dweller") that I had seen in Seal Bay a few weeks ago, with their companion boat, a KK39 "Waterford". When I met them again at the dinghy dock waiting for the launch to take them back to their boat I offered them a ride in my dinghy.
