Join us for a 1,000-mile offshore adventure from St. Vincent to Sint Maarten and back via Barbados, from November 29 to December 12, 2026. Two legs are available, each with its own mix of island scenery and open-ocean sailing:
- Leg 1 departs St. Vincent after a day of familiarization. It follows the Windward and Leeward Islands to Sint Maarten, covering about 500 miles.
- Leg 2 departs Sint Maarten and heads offshore toward Barbados. After rounding Barbados it returns to St. Vincent in a continuous 500-mile offshore passage.
BOSS offers ASA 106 and 108, and Sail Canada Advanced and Offshore certifications, on both legs. Leg 1 is better suited to Advanced certifications because we'll be in sight of land most of the time. Leg 2 is largely offshore, out of sight of land. Space is limited.
The owners of the yacht are preparing to take part in a future World ARC, so the curriculum includes activities that support that goal.
Sail waters contested for centuries by European powers and home to generations of buccaneers. Today they're enjoyed by island residents and by visitors who come for Caribbean sun, warm water, trade winds and beautiful scenery.
Vessel: Inconceivable, a 4-cabin 50′ Leopard catamaran.

- ASA 106 / Sail Canada Advanced Cruising (Leg 1 preferred)
- ASA 108 / Sail Canada Offshore Cruising

Leg 1
St. Vincent → Sint Maarten
Nov 29–Dec 5, 2026 · ~500 nm along the Windward and Leeward Islands
See the Windward and Leeward Islands, known to generations of explorers, buccaneers and cruising sailors. We chose Sint Maarten as the changeover point because it's one of the easiest islands to fly into. There should be time to loop around most, if not all, of the Leeward Islands.
