Nautilus Undersea crew is so nice, diving logistics are smooth, and the food is fantastic. The water is colder (68-72F 2024 late June/early July). We were in drysuits and glad we did. The boat has HP100 steel tanks for extra which is a nice bonus for drysuit weighting! The boat is on the older side and can tell its age. I like that there are only 16 divers, so we get to know everyone, and it is not chaotic. We saw many mantas and sharks (white tip/silver tip), a few hammers and dolphins, and lots of fish. We are lucky that the current is not strong and sea is mostly calm :)
