Wonderful excursion with a great crew! - Had amazing time on the excursion with a Captain Vic and Phillip! The catamaran was massive with tons of indoor shaded space and great spots to tan outside. Vic recommended the perfect travel plan for us with incredible snorkeling sights and Phillip was super helpful in finding sea creatures and great spots for us to swim. We truly had a wonderful time cruising the islands and highly recommend!

Best private boat tour - We did a 50 foot private catamaran ride. It was perfect! The waves were massive and the but rode them very well. They took us to a calm area for snorkeling which was amazing. We saw tons of fish, sea turtles, and a sting ray. The water is simply amazing and crystal clear. Then we went to a restaurant on a private island that had some of the best food. We loved it, loved that it was just us. Our captain JW and first mate Chloe were phenomenal. They took very good care of us, made sure we had fun and had drinks!

Circumnavigating St. John - We had an incredible experience circumnavigating St. John on a perfect day. JW and Liv were so helpful and knowledgeable. The snorkeling locations were excellent as we saw a huge variety of fish, sharks, and turtles. Liv snorkeled with us and was able to find an octopus. JW told us many stories of wrecks and prisoners on the island. We had so much fun at Lime-Out. The whole family had all of their needs met and questions answered. I would highly recommend this tour for a full day of snorkeling, cruising, and relaxing.

Absolutely Unforgettable Experience with Seas The Day Charter! - We had the most incredible day on the water with Seas The Day Charter! From the moment we stepped on board, Captain Alex and Alicia made us feel completely at ease and genuinely welcomed.
We had a big group that included young kids and grandparents, and they handled everyone perfectly. Captain Alex was knowledgeable, calm, and so intentional about making sure we saw the best spots. And we did, including SEA TURTLES! Watching them in their natural habitat was truly magical.
Alicia was phenomenal as well. Every little need was anticipated and taken care of with the warmest hospitality. Whether it was helping the kids, assisting the grandparents, handing out drinks, or making sure we were comfortable at every stop, she did it all with a smile.
What stood out most was how safe, relaxed, and special they made the experience feel. It wasn’t just a boat ride, it was a core memory for our whole family.
If you’re considering a charter, don’t hesitate. Book Seas The Day and ask for Captain Alex and Alicia, you will not regret it!
We are already talking about when we can go again! 🌊🐢☀️

Amazing day on SY Levithan!! - We had such a great time with Captain Alex and Alicia cruising around St John! We went to some amazing snorkeling spots, had a great lunch at Lime Out (the swim up taco bar), and just enjoyed chilling on the boat with Alex and Alicia. Alicia was so attentive to everyone in our party and kept our rum punch topped off. I highly recommend Seas the Day and especially Alex and Alicia!! The Rowlinsons

Best excursion of our trip! - This was the very best part of our 12 day Mediterranean cruise. The hospitality and service of the crew was exceptional and the food was amazing! They provided anything we asked for. Above and beyond… 4 years later, we still tell people to book this!

Terrible experience - Viator did make the original mistake by not cancelling a prior reservation we made properly, so we were very late in getting on this tour because of the mix up. That being said, the captain of the boat was extremely rude and off putting. Her name was Maddie. We spent half the time on the boat tha we were supposed to (again not their fault) but they didn’t offer any refund or compensation whatsoever. Would never recommend this company based on their customer service and staff alone.
