1981 Formosa 51 Ketch ‘KUAN YIN’ | Classic Bluewater Cruiser with Extensive 2026 Upgrades
KUAN YIN is a substantial 1981 Formosa 51, combining classic bluewater cruising credentials with significant recent investment. Her traditional ketch rig, long cast iron keel and keel-hung rudder create a robust setup for offshore cruising. New teak decks were laid in 2021, while 2026 has brought an extensive programme of maintenance, servicing and upgrades.

Key works include completed osmosis treatment and a full overhaul of the Ford Lehman 120hp diesel engine. The 2026 programme also includes underwater hull preparation and antifouling. Meanwhile, numerous smaller improvements cover the mechanical, electrical, plumbing and tankage systems. Exterior woodwork and deck fittings have also benefited from extensive refurbishment.

Her ketch rig features a 65ft wooden main mast from 2019 and a 45ft mizzen mast from 2024. A comprehensive North Sails inventory supports versatile cruising, while recent works include professional sail and rigging maintenance. Navigation equipment includes Simrad chartplotter and radar, AIS and a comprehensive range of sailing instruments.

Below deck, the Formosa 51 provides accommodation for six across three cabins. The spacious aft master cabin complements two heads, a generous saloon and a practical galley. Traditional timber joinery and a wood/coal stove add warmth and character, while the layout provides the space required for extended cruising.

With substantial recent investment and proven bluewater credentials, KUAN YIN presents an appealing opportunity. This Formosa 51 combines traditional character with the equipment and capability required for serious long-distance cruising.

The condition or level of safety equipment on board is not to be negotiated on following survey. It is likely to be listed by most surveyors but is not structural or an integral working part of the vessel and is not to be used to further negotiate the price down after survey. We strongly suggest that for your own personal safety that when purchasing a yacht you provide new safety equipment rather than relying on second hand gear.

Should you become the new owner of this yacht then the responsibility to re-register or update official bodies for items such as EPIRB, VHF, MMSI or AIS becomes yours.
