Took my family who was visiting from Sweden here and they LOVED it, were raving about it afterward. They've visited SF many times but this was a unique experience. It was early/mid September and we got fantastic weather. The crew was very friendly and professional. This was a bit more adventurous than I expected, with the amount of salt-spray and tilt of the boat, but I haven't done much sailing so that's just part of the experience. Bring a good camera with you and don't be afraid to use it, you can get some fantastic shots from aboard the boat, both of scenery as well as anyone who joins you on the boat. They provide some warm jackets so that you don't have to lug one around all day just for this one event. Two drinks are included in the tour, which is a nice little touch. If you're lucky you can find a Groupon for tour, but it is definitely worth full-price if you can't.
