Sonic Charters is a St. Thomas–based boat charter company operating out of Nadir, St. Thomas. The company provides private and shared day charters across the U.S. and British Virgin Islands, offering a fleet that includes powerboats, a luxury catamaran, and multiple yachts such as a 58' Princess and 50' Sea Ray Sundancer.
Sonic Charters serves groups ranging from small parties to larger family gatherings: some vessels accommodate up to 12 guests, a 32' Intrepid option holds up to 9 passengers, and the Enchantment listing notes seating for up to 18 (commonly capped at 12 for comfort). All private charters include a Coast Guard–certified captain and crew who act as on-water guides and servers. Standard inclusions vary by vessel but commonly feature high-quality snorkel gear (including kids sizes), open bars or beverage service, breakfast and snacks on select yachts, sound systems, and onboard comforts like sunpads and shaded areas.
Sonic Charters offers the shared "Triangle Trip" — an 8-hour island-hopping excursion visiting the Indians, Norman Island, and Jost van Dyke — alongside fully private charter options on luxury yachts and catamarans. Pricing notes for some trips state fuel, captain’s gratuity, and customs fees (for BVI travel) are additional. Sonic Charters emphasizes experienced local captains, well-equipped boats, and customizable itineraries to create memorable day-charter experiences in St. Thomas, St. John, and the British Virgin Islands.
