Go early enough
so that you can return to the bay if you need to. You are right that the majority of people anchor in the area about half way down the east side of the south lsland. However, the anchorage is basically an open roadstead (sp?). If a swell is from the north or the wind is too far north it gets pretty rolly, and you may want to go somewhere else. But, do go it's an interesting trip. The last time we stayed down there, we were boarded by a young sea lion while we were eating. He landed on the cabin house clearing the life lines to get on board. We had to entice him off with a piece of steak, then he tried coming up the swim step. Our dog was quite excited about it. As far as the dingy and exploring, I think you can see most of what is there from the big boat. But, there is some diving out there so you might be able to do some snorkling (it's way too cold for me).Go, have a good time, we did Mariners Cove over the holiday and had a good time.dwains/v Dancyh 340
