We just sailed the Winifred last week from St Thomas. It was a full day tour and the MOST AWESOME experience!!! My kids brought back pictures of them snorkeling with sea turtles and Manta Ray. Capt Sharon made us lunch as well. We also had open bar for the day. WOW!!! I was toasted!
The rate was $100 per person, but since I also brought along 2 of my clients, she only charged me for 3 people instead of 4.
The above recommendation seems to be a fit for your party, though.
