Fantastic Catamaran Day
jskowronski, October 2026
We had a fantastic time on the catamaran. This is the second time we’ve booked with Seas the Day Charter for a cruise excursion and both times, our family has loved it and had one of the best days of the cruise. Captain JW and First Mate Liv were great, made everything super comfortable, and made sure we had a fantastic time. The boat itself was perfect and we were able to relax and do some great snorkeling and swimming. We’d highly recommend and will plan to use them again in the future.
★★★★★Tripadvisor review
The best hours of our trip! Great company to work with and the crew was beyond what we could have hoped for!
GrannieB12, October 2026
What an amazing experience for our whole family! JW and Lindsay were so professional, friendly and informative. My only issue was that we couldn't stay longer... It was a trip beyond my grandkids' dreams! I loved that they arranged the trip around what we wanted to do and offered great suggestions. I HIGHLY recommend this tour!
Response from the operator · Hope S
We are so happy to hear everyone had a great day on the water with JW and Lindsay! Glad your Grands had fun too! SEA you next time!
★★★★★Tripadvisor review
One in a lifetime catamaran experience
avan450, September 2026
This was a once in a lifetime experience. Captain alex and liv were the most incredible guides and crew. they took us to secluded snorkeling spots, where we were able to see wild sea turtles, urchins, lobsters, moon jellies, and a lavish coral reef filled with fish. they taught us so many tips about snorkeling, boating, and the islands in general. On top of it, they served us cocktails, made sure we were safe and comfortable, and got plenty of pictures. You can’t beat an excursion with these 2 and seas the day.
Response from the operator · Hope S
Alex and Liv both truly enjoy spending time with our guests and sharing their knowledge. Thank you for being such a fun group!
★★★★★Tripadvisor review
11/10 experience!
annasX6392DV, September 2026
Can’t speak highly enough about Captain Alex & Liv. They were so knowledgeable and accommodating. Liv even dived into the water to grab my sunglasses when I dropped them while swimming. Definitely will be booking again!
Response from the operator · Hope S
Liv is part mermaid and can certainly retrieve "lost things" from the bottom of the sea! Glad you all had a great day!
★★★★★Tripadvisor review
Amazing
C6458JKjacksond, September 2026
Captain Alex gave a brief informational speech before every stop telling us what we should be on the lookout for, and where to go. Liv was also extremely knowledgeable, helpful, and very friendly. We saw sea turtles, amazing blue water, had the best mahi sandwich, and saw a shipwreck! The rum punch was also amazing. We will be coming back to st Thomas, and will be booking this charter again.
Response from the operator · Hope S
Safety First; then its all fun! Thank you for sharing your day with our crew; they had a fabulous day with each of you!
