Smooth Sailing! - Captain JW and Alecia made our trip fun and interesting. They took us to beautiful snorkeling places and beaches and we enjoyed a wonderful lunch on Lovango. The catamaran Sirena is a spacious boat with ample seating in both shady and sunny places. I would highly recommend this trip to anyone wanting a special voyage with an attentive crew on a well equipped boat in the beautiful Virgin Islands!

Amazing Experience - 10/10 experience! JW and Chloe did an amazing job showing us all the fun things the waters and beaches have to offer. We stopped at several spots to snorkel and were able to see all kinds of sea life, including sharks, turtles, and sting rays! Chloe did a great job making sure each of us had our drinks filled, and even dove in the water and rescued my mom’s cell phone! I wish we could have stayed on the boat longer. I’d recommend the charter to everyone. It was a great addition to our vacation.

This is the best half day... - This is the best half day excursion. What can be better than seeing the islands from the beautiful turquoise Caribbean water?!!! We had the good fortune to have Captain Maddy and First Mate Philip on our boat. They were so fantastic! Professional, fun and very attentive. Thank you both!!

Amazing day w/ Brody and Lindsay - We had an awesome experience on Seas the Day. We booked a full day. We stopped and snorkeled at 3 different coves and at Lime Out for lunch. We saw a ship wreck, sting rays, sea turtles, various fish, and even swam with a dolphin! Captain Brody and Lindsay were both great. They were very knowledgeable and friendly and treated our family so well. We couldn't have asked for better people to spend a fun day with. We didn't want the day to end, and have wonderful memories.

Enchanting catamaran ride!! - My 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!

Great crew, but the boat is absolutely NOT the luxury boat pictured - Let’s start with the fact that there was absolutely nothing "luxury" about this boat charter. Unless the photos in the listing were taken years ago, the boat we received was definitely not the boat pictured. It was falling apart, run-down, and felt like a complete bait-and-switch. We paid $2,295 for a full-day charter (9 AM - 4 PM) and expected a nice vessel, not a piece of junk. Though it advertises a capacity of 12, I have no idea how it could comfortably accommodate that many. It felt like because we had a smaller group, they gave us the crappiest boat in their fleet regardless of the premium price we paid. Multiple bathrooms were onboard, but only one worked—and even then, only the toilet functioned, not the sink.
​Furthermore, the amenities are bare-minimum. Drinks were limited to Coke, Diet Coke, Sprite, rum punch, and Presidente beer. Water was served from a large jug rather than individual bottles, and no snacks were provided at all—you have to bring all your own food. They are also entirely inflexible with logistics, refusing any pick-ups or drop-offs outside of Red Hook. For this price point, the value is incredibly low compared to other charters that offer much better accommodations.
​The saving grace of the entire trip was the crew. The captain and his deckhand were wonderful, incredibly nice, and provided great service. They made sure we got to experience exactly what we wanted: we visited a beautiful water-access-only beach, spotted a sea turtle, and had a blast swimming and jumping off the boat. We've done several private charters in the past, and while this crew was top-tier and met all expectations, the boat itself was a massive, expensive disappointment. We managed to have a great time, but management seriously needs to update their listing to reflect reality.
