Meet SeaQuinn — Exceptionally clean 3 cabin Owner’s Version | ICW-Capable | US Documented and Duty Paid
SeaQuinn represents an opportunity to acquire a thoughtfully upgraded, meticulously maintained cruising catamaran owned by an experienced captain. Designed for comfortable long-range cruising while maintaining practical access to the U.S. East Coast Intracoastal Waterway, she blends autonomy, redundancy, and true liveaboard comfort into a highly capable platform.
Having cruised extensively between New York, Florida, the Abacos, and the Exumas, SeaQuinn has proven herself as a reliable and comfortable passagemaker equally suited to seasonal migration, extended Bahamas cruising, or liveaboard exploration.
Her systems upgrades reflect real-world cruising priorities — reliability, ease of operation, and independence.
