The engine hum is a steady, confident heartbeat as Silver Cat eases away from the National Park dock in Cruz Bay. Salt stings your lips and the horizon opens wide: a scatter of green-backed isles, reef fringes that flash turquoise, and the faint outline of St. Thomas across a strip of blue. Onboard an Aquila 36 configured for twelve, the day unrolls like a well-planned route — breakfast laid out on polished surfaces, a high-end bar warming up by mid-morning, and a crew that knows where the quiet shallows hold the best fish and the sun-lit sand bars call for a pause.
