5.00We had a great day with Captain Judi and Megan. Megan taught my daughter so much about marine life and helped her feel comfortable snorkeling. It was her favorite part of our trip to STJ! Thank you both for a great day on the water. We will definitely book again on our next trip and hope our paths cross! 🩷🐢🦈

5.00We had an awesome day with Brodie taking us around to a few different beautiful spots here in the USVI. Brodie let us plan our day how we wanted and offered suggestions to some awesome spots! The boat was spacious, clean, had a bathroom, and offered plenty of drinks and snorkel gear. There was also a Bluetooth sound system to connect your own music.
Do the all day cruise!

5.00There was a group of 7 of us from Detroit and we had the best time with Captain Dave! The catamaran (Gemini) was truly amazing on the beautiful Caribbean waters, the Rum Punch was delicious, the beers were plentiful and the Captain was very attentive and accommodating. Picked the best spots for us to see turtles and fish! Thank you for an amazing day out Captain Dave!!!

5.00Capt. Dave was a very gracious and accommodating on our full day trip around St. Thomas and St. John. He took us to great snorkeling sites and mixed a fine rum punch as well! A day on the water sailing or motoring around these islands, especially St. John NP, is a must do when visiting. You will make beautiful memories. Capt. Dave takes care of it.
Great day at sea

5.00We are four couples staying on St. John. The private full day sail was a great way to explore the island and Captain JP took great care of us! The Mazu worked great but it was a little rough around the edges. We highly recommend!

1.00The experience it self was nice, only because the group I was with made the best of it. We paid for a 40ft boat and was put on a 36 got boat. the crew member name was Alex and he was very rude a passive aggressive. The boat was dirty and not only that 5 minutes into the ride an alarm started sounded and this man says “oh sh*t” then starts panicking. He told us to shut up as he was trying to figure out why that alarm was on. He called someone, a man showed up with second boat and offered to switch boats and Alex told them we were fine. Meanwhile the actual boat and dinghy we were using to get dropped off/ picked up at the beach was stuttering and cutting. The alarm was on because the boat was filing up with water. He didn’t offer us any beverages until we got to the first stop which was approximately 1hr. We debarked late, then stopped I the middle of the ocean due to the alarm. The whole excursion was rushed because he knew the boat was messed up we got back a half hour early than scheduled. I called to complain to the manager and she told me that we were too drunk to remember anything. The only drink offered was rum punch and 6/8 people on my group turn it down bc it was nasty. He offered us one cup of water and that was all. The man was just flat out nasty and came off prejudice bc when we got to the “turtles” he stopped the boat and told us we had to swim to the buoy that was 150ft away from the boat, refusing to allow passengers to use the floating noodle. We asked if he had nausea medication and Alex told us that it was a drug free/ smoke free environment but we saw him take two identify pills. Do not book this excursion.
