The Island Flyer slips free of American Yacht Harbor and the harbor's hum falls away, replaced by the slap of wake and a bright, flat horizon. Within minutes the water changes from harbor green to the clear, Caribbean blue that dares you to swim, and the captain already points toward a shallow reef where parrotfish graze and the turtle traffic is daily.

The Island Flyer slips free of American Yacht Harbor and the harbor's hum falls away, replaced by the slap of wake and a bright, flat horizon. Within minutes the water changes from harbor green to the clear, Caribbean blue that dares you to swim, and the captain already points toward a shallow reef where parrotfish graze and the turtle traffic is daily.
This short crossing threads the volcanic backbone and coral shoulders of the Virgin Islands. St. John’s reefs are a living edge of geology—ancient lava capped by coral growth—now protected in much of the Virgin Islands National Park. The bays you visit—Maho, Trunk, Christmas Cove and the smaller cays like Lovango—carry a layered human history too: A.D. Taino pathways, European colonial routes, and 20th-century conservation that set aside these beaches for public use.
Expect two snorkel stops and one beach stop in a four-hour semi-private trip (max 12). The crew outfits you with masks and fins, briefs on reef safety, and times entries to calmer waters when possible. Seas and wind steer the itinerary—Honeymoon Beach or Hawksnest are frequent landings when swell allows.
Practical notes: arrive at the Seas the Day departure lounge at American Yacht Harbor 15 minutes early, bring a towel, reef-safe sunscreen, and a small dry bag. If you’re prone to motion sickness, choose morning departures when seas tend to be flatter. The trip is accessible to confident swimmers with a moderate level of fitness; expect short swims and ladder exits from the boat. The islands offer vivid coral gardens, friendly crew-led instruction, and a fast, uncomplicated way to experience St. John’s best shallow-water snorkeling and beach time.
You should be comfortable in open water and able to swim short distances; flotation devices are often available and the crew monitors conditions closely.
Trips are subject to cancellation for unsafe sea or wind conditions; full refund is standard if canceled 24+ hours in advance or by the operator for weather.
Yes—masks, fins and snorkels are provided, though many guests bring their own for fit and comfort.
Children are welcome but infants may need to sit on laps and all minors require supervision; check age rules when booking.
