I have thought about this because I have an old engine and according to the PO it has failed a few times and had to be sailed in. Fortunately, I am only 2 slips from end of the dock. Unfortunately (as Goldenstate also said), Sausalito can be a windy place and it in the summer afternoon it can be blowing 15-20 down the fairway (so you are headed in to the wind).
Given my experience with this boat (very little), if it was windy, I think I would try to wait it out at anchor as others suggested. another option is to call vessel assist. I am kind of wondering though how they would tow me safely to the slip (?). it would probably require more of a tugboat approach- I don't know how the vessel assist tow boats are equipped.
If it was light winds, I think I would try to sail it in on partially furled jib alone (no main). If I can make the turn into the fairway (headwind) at 3.5 knots or so and then blow the jib, I think it would certainly be possible to coast into the slip to port with the 90 degree turn. I do have a lot of practice jumping off the boat while it is coming into dock, so I would leave both lifelines on both sides open and grab the boat at the dock as a jumped off (to the closer side). I know some people think that is dangerous, but am comfortable with it.
