I found this description of a 7 hour sailing excursion, don't know if it is the same one, but probably is:This schooner, beautifully equipped for your comfort, will take you sailing on the most beautiful waters you will find anywhere. With a host of islands surrounding it, our boat lets the winds glide you to Virgin Gorda's famous Baths for snorkeling. From there you will sail to Cooper Island and revel it is seclusion. It may be, though, that the winds are saying Norman Island, another wonderful destination. Here you have the chance again to enjoy the beach and perhaps find the lost treasure of Long John Silver. The Caves will provide the perfect snorkel. Whatever your destination, you will have a marvelous time and wish you would never have to leave.
The captain and the crew will make sure you feel like VIPs as they cater to you all day long. Somewhere along the 80 feet of deck space you will find your spot to relax and sip your rum punch while the crew does all the work. A delicious freshly prepared bbq lunch with two salads is served aboard, with complimentary beers, sodas, fruit punches, chilled white wine, iced water and rum punches are served all day. Your snorkel gear and vests are included - what more could you ask for?
We did a snorkel to Norman Island and one to another place close to Norman. We did these through the ship and they lasted about 4 hours. The best tour we had was asking one of the taxi drivers how much he would charge to take us around the island. He charged us $40.00 US and took us to various spots, we had a couple of beers in some local bars, he let us out on a couple of beaches, and told us a lot about Tortola that we would not have learned through a cruise. He let me take pictures whenever I wanted, and made sure we were safe. Tortola is a beautiful island and I hope you enjoy your cruise!!
