Gartside 18 Gaff Sloop

Description

The Gartside 18 Gaff Sloop, Design #139 by Paul Gartside, is a graceful, beamy centerboard daysailer that captures the essence of traditional English working boats with a modern twist for accessible home construction and family-friendly coastal cruising. Introduced in the 1990s as part of Gartside's stock plan catalog, it draws inspiration from classic cutters like his #107 Skylark and #113 Jessie but stretches to 18 feet for enhanced stability and capacity, featuring a gaff-rigged sloop sail plan that's efficient in light airs and forgiving for short-handed sailing. Ideal for protected waters—bays, lakes, or nearshore passages—this wooden beauty emphasizes elegant lines, a shallow draft for beaching, and a small ballast keel for righting moment, making it a favorite among wooden boat builders for its balance of performance and simplicity; fewer than a few dozen have been completed, with plans available for $100–$200 USD from Gartside Boats.

Custom sail calculations are not possible for this boat as no I, J, P and E dimensions are available.
