Glen L 7.9
Description
The Glen-L 7.9, a high-performance 7.9-meter (25'11") trailerable racing sloop designed by Glen L. Witt in the late 1970s and offered through Glen-L Marine Designs, stands as one of the firm's most ambitious amateur-built plywood sailboats, blending one-design racing DNA with coastal cruising capability for speed-hungry builders chasing PHRF fleets or weekend overnights in the Pacific Northwest, Great Lakes, or Gulf Coast. Measuring 25'11" LOA (24' LWL) with an 8-foot beam, 1'6" draft (board up; 5'6" down with a 1,200-pound lead bulb keel), and 3,800 pounds displacement, it’s engineered for planning performance and easy trailering (under 5,000 lbs. on a custom bunk trailer), launching via standard ramps without a crane.
