5.00We had an amazing time aboard palhana! Annmarie (hilarious) and Kahlia (“call-ya”) are 5 star and absolutely wonderful. They took us to all the best snorkeling spots, anticipated all of our needs, and made us laugh. I cannot recommend Seas the Day enough! This is our second time sailing with them and we will be back lots more.
GReat day in the water!!

5.00Such a good time! Captain Rusty was the best, overall just a good person, but also a great tour guide and instructor. He was very good with the kids too. The views were amazing. We got to see a sunken ship wreck, swim with sea turtles, laugh and dance and sing on the boat. Truly an amazing experience. Also the Mahi Mahi on Honeymoon beach was the most delicious fish I've ever tasted. I highly recommend this experience.
Great Day Charter

5.00Had a great tour day with Captain Alex on 1/8/25. We were on the Island Flyer and it was the perfect size for our group of 10 adults. As the one in charge of putting our group charter together everyone in my group told me how much they enjoyed the captain, boat, snorkeling, and stopping to each lunch at Dinghy’s on the beach. Thanks for a great charter!
Seas be day and Captain Glen were amazing!

5.00Captain Glen was absolutely amazing. He made the day around what we wanted to see. He was very informative also. We loved learning about the history of the islands. I highly recommend going with this company and Captian Glen! My kids also loved the day so much. It will be a day we always remember.
Awesome adventure

5.00Captain Wallens was fantastic. Gave a safety briefing then asked us what we wanted to do. Was accommodating and knowledgeable. The kids and adults had a great time. We swam with turtles, swam to a private beach, did some snorkeling. We maximized our time. Wish it had been longer. Thank you Cap Wallens!
Amazing Captain!!

5.00Captain Wallens was very knowledgeable and attentative to all on board. He made sure all members of our party had a great time. He was patient when necessary and even went above his duties to get some snorkelers comfortable in the water. We saw turtles and lots of fish. We could not have asked for a better Captain.
Like snorkeling in an aquarium

5.00Captain Amanda was awesome. We chartered the MV Poseidon which is a 36’ twin vee with plenty of room for 12. We requested a snorkel trip to St John and we couldn’t have asked for anything better. It was like snorkeling in an aquarium. I highly recommend.
Beware of those pesky surprise boat inspections!

1.00Seas the Day Charters cancelled our half-day catamaran tour the night before (not the DAY before). At 7:36PM. While I was on a cruise ship in the middle of the Atlantic. Thankfully I had purchased the ship’s WiFi package so that I received their cancellation text. They said their annual “surprise” boat inspection came up. (They didn’t know that earlier in the day?) So they offered me either an earlier time slot (when my ship would still be at sea), a different day (my ship would only be there on the day I booked), or a refund. I explained I would have to take the refund, as the first two options wouldn’t work for the above reasons. They offered no assistance in booking an alternative tour when I asked. I had to work with Viator for an hour from my cabin to book a new tour for the next day, and most of the good ones were sold out by then. Meanwhile Seas the Day Charters didn’t inform our would-be captain (who was very nice) of the cancellation because he texted me the morning of to finalize details. When I told him Seas the Day had cancelled our tour, he was surprised and offered an upgrade at no additional charge to their 50-foot boat. But we would have had to pay cancellation fees for the new tour we booked, so I declined. If Seas the Day Charters had done full research and presented us with all options at the beginning, this whole mess would have been avoided.
CAPT Amanda Rocks

5.00CAPT Amanda was absolutely the best; she is exceptionally knowledgeable of the Islands history, geography and aquatic life. She’s got a very personable personality, but don't mistake for a minute that safety is the foremost serious side of her professionalism. Highly recommend her!!!!
