Left promptly at 8:30am. Smaller boat with 12 or so on board. Captain & mate were friendly and very helpful. Very clear on the rules (eg, don't touch the turtles). Very clear on what to expect (eg, you're gonna get wet, you'll have a full hour in the ocean, this is how the snorkle works).
We could stow things we wanted to stay dry in a big locker -- very helpful.
A small catamaran like this can be a little barfy and you need some agility to get situated & move around. But I'm 67 and had no problems. A few other older people also did just fine.
If you want a nice, big comfortable boat, this is not your tour. But if you want a cool experience that feels like a real sail, and are looking for value, then go for it. I'd recommend this for anyone with kids old enough to handle themselves well, as we as for any adult who can still get around a bit.
Oh, the turtles were fantastic, too.
