Construction
Sources
Only 4 hulls built, and specs genuinely vary between them: the first three were epoxy/E-glass with carbon-fiber reinforcement (used here), the fourth built entirely in carbon with Kevlar on the bottom and outboard sides -- lighter than the ~33,951 lb (15.4 tonnes) light-ship figure used here, which is quoted alongside a self-consistent SA/D ratio of 36.6 for mainsail (1,755 sqft) + solent jib (624 sqft). A separate technical-specifications listing (Multihulls World) gives smaller main/genoa figures (1,259/624 sqft) for the same model, likely reflecting a different one of the four hulls or a different sail inventory; used the katamarans.com figure set for internal consistency. Boards-up draft ~3 ft, boards-down (used here) 11 ft. Designed by Morrelli & Melvin for Gunboat founder Peter Johnstone; built by Harvey Yachts, Cape Town, South Africa. Carbon mast, ~85 ft. Exact production years not confidently pinned down given the small, variable-spec run; left year_end null. Verified 2026-07-12. [Rudder/tankage/electrical update, 2026-07-16]: Twin retractable high-aspect rudders (spade-type; shoal-draft performance design) -- construction material not independently confirmed. Fuel 2x475L=950L/~251gal total. No water/holding-tank or electrical-system capacity data found in available sources.
