The Lady Washington is one boat on the west coast that uses volunteer crew each summer. They are based in Aberdeen, but this next week they will be in Port Townsend at the wooden boat festival.
Lady Washington is a replica of the first American ship to sail in Washington I think, but anyone who has seen the Pirates of the Carribean movie saw the Lady Washington and her crew as it was repainted and sailed to be in the movie last year.
Also there are some people who do not use engines here in Bellingham. One I saw used oars in his 28 foot boat that was about 7500lbs displacement. I have some reservations about depending on oar power in some of the currents around here. Not to mention useing sweeps in a tight marina environment, but if you picked your days to sail and stayed out anchored, it could work.
