5.00We had an incredible day on the waters with Captain Phillip. Multiple extraordinary snorkeling stops with sightings of sea turtles, spotted searays, reef sharks, squids, and more tropical fish than you can imagine. The Gemini was perfect for our 6 adults and one infant. The rum punch was perfect and captain Phillip was a great host! Thanks for the perfect Father’s Day!
Amazing day at sea.

5.00What a fun filled day with Captain Phillip on Mazu with Seas the Day charters. His level of service, attention, fun facts and marine biology knowledge was exceptional. We wanted to snorkel spots others may not … St Thomas … Christmas Cove with turtles and rare spotted eagle ray … Thatch cay for the caves and then Lovango Cay to finish the day with chill time to enjoying calmer waters and a final snorkel. And To maximize our snorkel time we enjoyed custom lunches from Tasty Sips and Bites provisioning in Red Hook. 🥪

5.00We took a full day excursion with SEAs the Day. Captain Phillip and mate Colette provided an excellent experience. Although they have proposed trip schedule, they willing adjust to the wishes of the customer. They were informative about the different islands and very attentive to our needs around libation/hydration, helping with snorkel equipment, and performing photographer duties. We had an all around great day!
Family Fun!

5.00We had a great day with Captain Judi and Megan. Megan taught my daughter so much about marine life and helped her feel comfortable snorkeling. It was her favorite part of our trip to STJ! Thank you both for a great day on the water. We will definitely book again on our next trip and hope our paths cross! 🩷🐢🦈

5.00We had an awesome day with Brodie taking us around to a few different beautiful spots here in the USVI. Brodie let us plan our day how we wanted and offered suggestions to some awesome spots! The boat was spacious, clean, had a bathroom, and offered plenty of drinks and snorkel gear. There was also a Bluetooth sound system to connect your own music.
Do the all day cruise!

The catamaran (Gemini) was truly amazing on the beautiful Caribbean waters, the Rum Punch was delicious, the beers were plentiful and the Captain was very attentive and accommodating. Picked the best spots for us to see turtles and fish! Thank you for an amazing day out Captain Dave!!!
