Design and Construction
David's Lancer 40 is a monohull of fiberglass construction, built predominantly of solid fiberglass with wood trim, a raked stem, and an angled transom carrying a fixed swimming platform. She carries a skeg-mounted rudder controlled by a wheel and a fixed fin keel, though one reference describes her as built with a long keel while the dimensional record lists the standard fin with 6.30 feet of draft; sources differ on keel type. Displacing 15,500 pounds with 4,500 pounds of ballast, her ballast ratio of 29 percent is higher than only 8 percent of similar sailboat designs, and her length-to-beam ratio of 3.33 makes her slimmer than 54 percent of all other designs. The Motion Comfort Ratio of 24.4 places her as more comfortable than just 24 percent of similar designs, so the hull form favors moderate cruising motion over plush steadiness.
Rig and Sail Plan
The boat is rigged as a masthead sloop with a Bermuda rig, and the numbers show she is dramatically overcanvased for her size class: she carries more rig than 99 percent of all similar sailboats, which indicates she is significantly overrigged. With the ISO 8666 reference sail the SA/D is 17.7, rising to 21.0 with a 135 percent genoa, and that sail-area-to-displacement relationship means she is faster than 54 percent of similar designs in light wind. The total sail area of 688.8 square feet is spread on a 43-foot mainsail luff and a 49.5-foot foretriangle, with halyard runs of about 111.8 feet. Her theoretical hull speed is 7.77 knots, and the displacement-length ratio of 181 categorizes her among moderate racers, with 79 percent of similar designs heavier than she is.
Accommodations and Layout
Herb David laid the Lancer 40 out as a center-cockpit cruiser with an inboard motor fitted for cruising, docking, and maneuvering. The angled transom with its fixed swimming platform extends the usable stern profile, and the wheel-steered skeg rudder places helm control aft of the central cockpit. The center-cockpit motorsailer configuration frames her as a liveaboard-capable coastal cruiser rather than a minimal weekender.
Performance Profile
The capsize screening value of 1.93 and the immersion rate of about 1,408 pounds per inch speak to a stable, moderately loaded hull whose wetted surface of 462 square feet is typical for a 40-foot cruiser. The combination of overrigging and a comparatively low ballast ratio means she derives weatherliness from sail power and hull form more than from deep lead, and her slim beam keeps her quicker than the majority of similar boats upwind in light air without claiming bluewater seakeeping superiority.
The Verdict
The Lancer 40 is a distinctive David-designed Power Sailer: heavily canvased for a 15,500-pound cruiser, slim-beamed, and laid out around a center cockpit with a stern swim platform. She rewards light-air sailing and easy docking with her inboard and wheel, but her short build window and modest comfort ratio mean she is a niche cruiser rather than a volume production stalwart.
Pros
- Significantly overrigged masthead sloop delivers light-wind speed ahead of 54 percent of similar designs
- Center-cockpit layout with fixed swim platform and wheel-steered skeg rudder
- Slim 3.33 length-to-beam ratio and 7.77-knot hull speed suit relaxed coastal cruising
Cons
- Ballast ratio of 29 percent betters only 8 percent of comparable sailboats
- Motion Comfort Ratio places her ahead of just 24 percent of similar designs
- Built only 1983–1985, limiting fleet size and spares commonality
