Ray and Kerper St Thomas vacation

Published on May, 2025

A perfect afternoon on the water!! Alicia and Megan made sure we each a beanbag seat and cold drinks for a very relaxing and comfortable sail. Captain Alex was fantastic and made sure we had a hassle free experience. We’d definitely use this crew and Seas The Day charters again.

Amazing UVSI boat charter

Published on May, 2025

This boat charter is completely first class! They took us to 3 amazing coral reefs, set up a wonderful lunch at an island resort, and provided us with everything we could possibly need along the way, especially their home made rum punch. I highly recommend them for any couple, group, or family who wants a fantastic Virgin Island experience.

We had a great time on...

We had a great time on our day cruise! Our captain suggested snorkeling spaces and lunch spots and were great bartenders!

FERRY, BRANCO, DOUGLAS PARTY OF 10

Published on May, 2025

We had JW and Alex on Tuesday May 6th 2025. What a fantastic day with them. We were briefed on all rules and safety regulations completely and off we went. Just a perfect day they were both professional, full of history facts about the USVI, fun and all about the safety. The rum punch was delicious. This was our second time using Seas the Day and it has now become something we will do each visit back. See you next year.
