About the Galway 36 Westerly Sailboat

Built between 1976 and 1982 by Westerly Marine, this Laurent Giles-designed cruiser represents solid British boatbuilding from the era when fiberglass construction was reaching maturity. The Galway 36 stands out primarily for its twin keel configuration, making it an excellent choice for sailors who frequent shallow waters, tidal areas, or prefer the convenience of drying out upright in harbors. With a displacement of 17,355 pounds and nearly half of that weight in ballast, this masthead sloop offers the stability and sea-kindly motion that makes extended coastal cruising comfortable. The twin keels provide good directional stability while allowing access to anchorages that would challenge deeper-draft vessels. Her moderate sail area and substantial build quality reflect the conservative British approach to cruising yacht design. The boat's comfort ratio of 33.87 indicates excellent motion at sea, while the capsize screening formula of 1.73 suggests good stability for coastal and offshore passages. Her hull speed of 7.37 knots is respectable for a cruising yacht of this displacement, and the 36-horsepower engine provides adequate auxiliary power. This design appeals particularly to cruising sailors who value seaworthiness, shoal-water capability, and the proven track record of Westerly's construction standards during their productive years.
