Dominica non-ship snorkel trip?

[sofietucker]

We'd done the ship's shorex a couple of times to Champagne Reef, as well all the rainforest, etc.  Lat time it was a small boat--maybe 10 pax--that took us to 3 places, ending at Smith's Bay(?). We want to do that again but cannot locate the operator, so we're on the hunt for something new... Anyone done a good snorkel trip recently?
