Finally took the ASA Keelboat course. (Had some bad weather so still have to make up a few hours sailing, but passed the test. Put tyne offer in on the 28' O'Day. Survey and Sea trials are supposed to be Friday. But today when the owner was moving the boat for haul out, he discovered a problem with the diesel heat exchanger. He's having it fixed. (Cracked elbow on the exhaust side?) May not be fixed in time to support Friday. May have to move survey to next week. At least the cracked elbow will be fixed!
