5.00My family including my two great grandchildren who are 2 and 1 had the best time with JW and Chloe. They were so accommodating from their the get go. We will definitely be asking for them again! Boat was very spacious and accommodated all 7 of us easily. JW let us choose what we wanted to do. We snorkeled and then went for a wonderful lunch at Lovango Cay. Can’t wait to do this again!
Exciting catamaran day trip!

5.00From start to finish, J.W. and Chloe made this such a great experience. We were traveling with little ones, and they made sure that the babies had a great place to keep cool and safely play while some of the adults enjoyed snorkeling. J.W. took us to the prettiest spot for snorkeling too! If he makes a recommendation, it’s worth listening to!! After snorkeling, he helped us find a great lunch spot and it couldn’t be beat! We would definitely recommend this and would do it again!!
Had a wonderful time!

5.00We had a group of 12 on a private cruise with Colette and Brodie who were absolutely wonderful. We had a great time, and the sail was so peaceful.
Half day trip wasn’t even long enough. Book a full day!

5.00We booked a 1/2 day excursion with Seas the Day while visiting St. Thomas for my sister's wedding. This was one of the most amazing experiences I have ever had (and my family agrees!). We were a group of 10 (I think and had a mix of adults and kids (ages 9-11). Captain Maddy and Olivia were so knowledgeable and made our day one to remember. My only regret is not booking the full day excursion I think, but the half day was perfect, too. For a slight bit more than the cost of the other catamarans (where you are shacked up with strangers), we got the whole boat to ourselves. They sent us a text ahead of time reminding us what to bring on the boat (they provide the snorkeling gear, a few soda options, a few bear options, and a delightful rum punch!) We brought coolers with drinks and snacks and had ourselves a delightful time; we got to bluetooth into the speakers and play our own music on the boat, and the rum punch they provided was AMAZING. During our excursion, we stopped at two locations to snorkel -- the first one had a shipwreck and we saw sea turtles, squid, various colorful fish, and even a nurse shark! The second location was a stone's throw from Little St. James (yes, THE island), which was pretty wild to see, but it had the most amazing coral reefs with lots of fish and urchins to take in. This by far was one of the most memorable experiences I have ever had and recommend it to anyone visiting St. Thomas!
Awesome custom experience

5.00Great small group custom sail. Went to 2 great snorkeling spots and a beautiful place for lunch. Picked up snacks and our favorite wine at the store around the corner beforehand. JW and Edwardo were fantastic, providing us with an awesome luxury experience.
AMAZING experience for our whole family!!

5.00This was an AMAZING experience!! We did a full day tour with our friends and kids while on Spring Break. JW & Eduardo were the best! They even made the safety talk at the beginning funny! They listened to what we had hoped to see and do that day and totally delivered! We got to three different snorkel sights and all were fabulous! We saw a ton of different fish and even saw turtles, rays, and a couple nurse sharks! We had our own snorkel masks but they were so helpful with our fins and got out other mask options when the kids wanted to try them. Speaking of kids…they were fantastic with them! We had six boys with ages 16-7 and they really took the time to chat with them, ask them questions, and answer the boys’ questions. We went to Lovango Resort for lunch, which was delicious and then to an amazing (and quiet!!) beach on St John. The service was amazing…both JW and Eduardo told us so much about where we were and what we were seeing and answered all our questions! The refreshments onboard were wonderful. Eduardo was there asking us what we needed right away. Overall it was definitely a highlight of our trip and we’d book again!!

5.00We had a great day with Maddy and Chloe! We came in on a cruise ship and spent the entire day on the catamaran. The taxi price to get to the port is a bit ridiculous, $375 round-trip for 11 people. We saw turtles at our first snorkel spot and lots of colorful fish at our 2nd stop. Maddy and Chloe accommodated us by sailing around Epstein Island, We couldn’t have asked for a better day!
