Sail from St.Thomas to St.John's beautiful Caneel Bay where you will spend time snorkeling with tropical fish at one of the premier spots in the USVI. Caneel Bay is just one of several possibilities for this trip and not always a definite stop ( time and weather dependent). We may snorkel a different location near this area ( Christmas cove, or Lovango). Captain Rob knows all the great snorkel spots and will always do his best to put you in the calmest waters.

This was so fun! My husband wasn’t feeling well at one point but Rob and Deb took amazing care of him. Made sure he had water at all times, also made sure everyone on the boat had what they needed. The hospitality was unmatched! Deb constantly filled our cups up with whatever drink we wanted, she offered us snacks after snorkeling too! Rob gave us some good dinner recs and told us some good info about the island. We would definitely recommend this to anyone!

The sailing trip was amazing and our crew was knowledgeable and friendly. We couldn’t have asked for a better excursion! We had fun snorkeling, saw many turtles and a plethora of beautiful fish.

Wonderful day with Captain Rob and Mate/Bartender/Tour Guide Deb. Deb was great with communication before the trip and it was easy to find them at the marina. We had a great sail to Great St. James and enjoyed snorkeling at Christmas Cove. Luck was with us as we saw a spotted eagle ray, several sea turtles, a lobster, an octopus, trunk fish, puffer fish, huge urchins, and many more beautiful fish. Thanks for a wonderful day and the suggestion to spend some time at Sapphire Beach afterwards. The tropical chicken sandwich was tasty! P.S. great tunes, Capt Rob!

We had a wonderful time sailing and snorkeling with Rob and Deb. They were amazing hosts, super friendly and very knowledgeable. We had a lot of fun chatting with them and learning about the islands around us while sailing. They took us to a terrific spot for snorkeling where we got to see sea turtles, a stingray, and a variety of beautiful fish. This was my first time sailing and it was a great experience, there were only two other people on the boat with us, which really made it feel like our own private excursion. I would absolutely sail with Rob and Deb again next time we are in St. Thomas. Also, the rum punch was delicious and we had some great laughs along the way. Highly recommend!

Rob & Deb were great hosts. The snorkeling was amazing. Their sailboat was so much fun. We had never sailed before. The rum punch was awesome. I would highly recommend them for a wonderful and personalized excursion. Deb even dove in to rescue my UV sun shirt.

Great opportunity to be on a real sailboat with two very experienced operators. Very different from sailing on a Cat (in a good way) and in a very small group. Rob and Deb were perfect hosts.

Great day on the water! Wonderful experience for our entire family on the boat and snorkeling with some beautiful sea turtles. Thanks for taking such good care of us! Your boat is lovely and we appreciated you letting us share a small part of your world for the day. Will look you up if we are on island again :)
