Very memorable time aboard the Serena! - This activity was the highlight of our stay in St. Thomas. We were a family of six, including an 7 and 2 year old. Everything from the booking to checking-in was smooth. The captain and first mate were accommodating and very knowledgeable. We spent our time on a turquoise beach with powdery sand and while snorkeling, we saw turtles, tons of fish and sting rays. It was an unforgettable experience - especially for the kids. On the sail back, the first mate had a lot of interesting facts to inform us about the local history. Overall, I would highly recommend this tour.

Amazing Family Adventure with Seas the Day! - We had an unforgettable day with Seas the Day Charters aboard the Leviathan! We're a family of four with two boys (12 & 15), and this was the perfect way to explore the beauty of the USVI. Captain Alex and First Mate Coleman were fantastic—super friendly, professional, and fun. They helped us customize a “choose your own adventure” day, and it couldn’t have been better. We snorkeled at several beautiful spots (Lovango Beach, Maho Bay, Cinnamon Beach, and Caneel Bay) and saw an incredible variety of sea life: turtles, southern rays, a spotted eagle ray, a nurse shark, jellyfish, barracuda, and tons of colorful fish. The water was crystal clear, and the boys were amazed the entire time. We also had a great lunch at Maho Bay, played games, spotted birds, and even tried Genip fruit! Highly recommend Seas the Day—safe, fun, and perfect for families. We’ll absolutely book again next time we're in the Virgin Islands!

Private half day yacht experience- enjoyable for the whole group - We had an unforgettable half-day private yacht experience with Maddie as our captain and Olivia as the first mate. Traveling with three young kids (ages 4 months to 5 years) can be a challenge, but Maddie and Olivia made the entire trip really fun. They were incredibly accommodating, kind, and attentive to our whole group. We explored a few beautiful snorkel spots and were lucky enough to see sea turtles and even a shipwreck. The boat was clean, comfortable, and well-stocked, and the entire experience was perfectly paced for both the adults and kids. Highly recommend for families or anyone looking for a personalized and memorable time on the water.

Very nice trip. Great... - Very nice trip. Great snorkeling and crew were excellent, especially the first mate, Liv. One thing to note, the beach options aren’t accurate. Captain said we couldn’t go to certain beaches like Trunk Bay because it was restricted from commercial charters even though the advertising for the experience lists Trunk Bay as an option.

- I started off sea sick and remained so for the duration of the trip, despite taking medication. This is not their fault of course. I do, however, feel they should have informed me of the best place to be in the boat. We started off in the front/bow on the trampolines on the bean bags. It started off pretty calm, then quickly turned rough. So rough that the front of the boat partially went under and we were hit with 4’ waves. It was rather terrifying. Our children, ages 7 and 11 were crying. My husband and I were trying to put on a brave face, but were rather terrified ourselves. After it ended, a crew member came to check on us. She said we went through the “wash machine” where the Atlantic meets the Carribean. It is notoriously rough she said, but didn’t expect it to be so “splashy”. The captain mentioned the winds were rather high the previous day which contributed to the added roughness. I feel, given the experience of the crew, the should have had a bit of an inkling that it would be “splashy “. “Splashy was an understatement. It was quite scary. After all this finished up, 5-10 min worth, all was calm. The crew was accommodating getting us beverages, hanging up our wet towels, snorkeling with us, and giving us recommendations for the rest of our trip. I wish they would have offered to take some pictures for us. It was something I didn’t think much about since I was so feeling so well. I am glad our kids put the beginning of the trip behind them and enjoyed their first snorkeling experience. My son is a bit scarred from how the trip started. Hoping he gets over this soon.
