Jacqui, our dive master, was super professional in making sure that we were well qualified, safe, properly equipped. He led our two dives, and knew the sites very well. They use a smaller Zodiac-like boat which was fine with us. We saw some other dive boats in the harbor, which looked more like party boats, that I am glad we avoided. The only thing negative was the fact that many people on the boat smoked. We've been on other European dive boat where that happens, but it's quite unusual for US/Caribbean divers.
