Design and Construction
The Lancer 40 is a fiberglass monohull, built predominantly of solid fiberglass with wood trim. She has a raked stem and an angled transom with a fixed swimming platform. The rudder is skeg-mounted and wheel-steered.
Sources differ on the keel. One reference describes a long keel, while the dimensional record lists a standard fixed fin keel drawing 6.30 feet.
The boat measures 40 feet overall, with a 33.67-foot waterline and a 12-foot beam. Her length-to-beam ratio of 3.33 makes her slimmer than 54 percent of all other designs. She displaces 15,500 pounds and carries 4,500 pounds of ballast. Her 29 percent ballast ratio is higher than only 8 percent of similar sailboat designs.
The Motion Comfort Ratio is 24.4, placing her ahead of just 24 percent of similar designs. Those figures suggest a hull form that favors moderate cruising motion rather than plush steadiness.
Rig and Sail Plan
The Lancer 40 carries a masthead sloop sail plan with a Bermuda rig. By the comparative numbers, she is dramatically overcanvased for her size: she carries more rig than 99 percent of all similar sailboats, making her significantly overrigged.
Using the ISO 8666 reference sail, her sail-area-to-displacement ratio is 17.7. With a 135 percent genoa, it rises to 21.0. That sail-area-to-displacement relationship puts her ahead of 54 percent of similar designs for light-wind speed.
Total sail area is 688.8 square feet. The mainsail luff measures 43 feet, the foretriangle is 49.5 feet, and the halyard runs are about 111.8 feet.
Her theoretical hull speed is 7.77 knots. A displacement-length ratio of 181 places her among moderate racers, with 79 percent of similar designs heavier than she is.
Cockpit and Accommodation Layout
Herb David arranged the Lancer 40 as a center-cockpit cruiser, with an inboard motor for cruising, docking, and maneuvering. The angled transom and fixed swimming platform extend the usable stern profile, while the wheel-steered, skeg-mounted rudder places helm control aft of the central cockpit.
Overall, the center-cockpit motorsailer configuration presents the boat as a liveaboard-capable coastal cruiser rather than a minimal weekender.
Performance Profile
The Lancer 40 has a capsize screening value of 1.93 and an immersion rate of about 1,408 pounds per inch. Her wetted surface is 462 square feet, typical for a 40-foot cruiser. Together, these figures describe a stable, moderately loaded hull.
The combination of a powerful rig and a comparatively low ballast ratio means she derives weatherliness more from sail power and hull form than from deep lead. Her narrow beam helps make her quicker upwind in light air than most similar boats, though that does not amount to a claim of superior bluewater seakeeping.
The Verdict
The Lancer 40 is a distinctive member of Herb David’s Power Sailer line: heavily canvased for a 15,500-pound cruiser, relatively slim-beamed, and arranged around a center cockpit with a stern swimming platform. She rewards light-air sailing, while the inboard motor and wheel support easy docking. Her short production run and modest comfort ratio, however, leave her as a niche cruiser rather than a high-volume production stalwart.
Pros
- Significantly overrigged masthead sloop delivers light-wind speed ahead of 54 percent of similar designs
- Center-cockpit layout with a fixed swimming platform and wheel-steered, skeg-mounted rudder
- Slim 3.33 length-to-beam ratio and 7.77-knot hull speed suit relaxed coastal cruising
Cons
- Ballast ratio of 29 percent is higher than only 8 percent of comparable sailboats
- Motion Comfort Ratio places her ahead of just 24 percent of similar designs
- Built only from 1983 to 1985, limiting fleet size and spares commonality
