I agree that I'd prefer not to do the Bottom Scratcher if it's an overnight thing. It's not a bad boat for a 1-day trip, but I can not sleep in the bunks. Talk about small!
Personally, I'd prefer a 1-day trip, preferrably on a Sunday, although if I get enough notice, I can take a Sat. off work. My weekends are open for now, so any weekend in Jan or Feb works for me.
I haven't been on the Pacific Star, but have heard very good things about it and would be interested. There's also the Psalty V, but it's only got room for 7 divers. It's a nice, fast boat, and being small, we'd be able to fill it so we'd have it for ourselves, which would be nice.
