Gremlin (UK)

Description

The Gremlin is a compact, general-purpose pram dinghy designed by British naval architect and boatbuilder Percy W. Blandford in the mid-1950s as an affordable, DIY project for novice builders with limited resources, time, and space, serving as a precursor to popular postwar plywood designs like the Goblin, Cadet, and Mirror dinghies. Measuring approximately 7 feet 9 inches LOA with a 4-foot beam and weighing just 60–80 pounds, it features a hard-chine plywood hull with a V-section forward blending into a shallow curve aft for improved wave entry and stability, a pivoting centerboard, and a simple lug or gunter sloop rig offering around 40–50 square feet of sail area for gentle planning speeds up to 5 knots in light breezes—ideal for solo adults, juniors, or as a yacht tender. Kit-built from three sheets of marine plywood using basic stitch-and-glue or nailed-frame methods (plans marketed via Light Craft magazine), the prototype debuted at the 1957 Earls Court Boat Show for £15.50 including sails and oars, enabling single-handed lifting, roof-rack trailering, and versatile use for rowing, sailing, or fishing in sheltered waters. Production was limited and plans are now scarce (available via Clark Craft or Blandford enthusiast groups).

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
