The bow slips free from the dock and the trade winds catch the Cosmos Mariner’s canvas; within minutes the shore shrinks and the sound of the engine is replaced by wind and water. On a clear morning the eastern approach to St. Thomas opens into a palette of Caribbean blue, and the pilothouse of this Robert Perry–designed 40ft vessel becomes both classroom and vantage point.

The bow slips free from the dock and the trade winds catch the Cosmos Mariner’s canvas; within minutes the shore shrinks and the sound of the engine is replaced by wind and water. On a clear morning the eastern approach to St. Thomas opens into a palette of Caribbean blue, and the pilothouse of this Robert Perry–designed 40ft vessel becomes both classroom and vantage point.
This private three‑hour sail out of Sapphire Marina follows a straightforward cruising route across the channel toward St. John, driven by steady easterly trades and reef‑lined coves. Geologically the Virgin Islands are uplifted coral and volcanic rock; from the water you’ll notice blocky ridgelines and fringing reefs that shape sheltered bays. Culturally the route threads past working harbors and beachside hamlets where local fishing boats and catamarans gather, a reminder that sailing here is both recreation and a way of life.
Expect a relaxed pace: crew will trim sails, explain points of sail if you want to learn, and offer bottled water, snacks and optional alcoholic beverages. The operator will sail only unless you request a snorkel stop—bring swimwear and reef‑safe sunscreen if you plan to jump in. Boarding is easy at Sapphire Marina (slip N20); the captain will brief you on safety, movement aboard and restroom access.
Practical tips: plan this trip for mornings or late afternoons to avoid the sun’s peak; seas are generally calm but bring a light wind layer. This private charter suits anyone comfortable on a small sailboat and looking for pure sailing without multiple stops—an efficient, scenic way to feel the islands’ wind and water up close.
This trip is a pure sailing cruise by default, but the crew can add a snorkel stop on request if conditions allow.
