Glen L Tango

Description

The Glen-L Tango, an 18-foot 6-inch trailerable overnight sloop designed by Glen L. Witt in the 1970s and offered through Glen-L Marine Designs, punches above its weight with a light, stiff, beamy hard-chine hull that belies its compact size, delivering brisk performance and family-friendly comfort for coastal daysailing, club racing, or weekend gunkholing in bays, lakes, or the ICW. Measuring 18'6" LOA (16'6" LWL) with an 8-foot beam and 1-foot draft (centerboard up; 4 feet down with 800 pounds lead ballast for a 40% ratio and comfort ratio ~22), it displaces 2,000 pounds, enabling easy towing behind a mid-size car on the Series 1700 trailer and solo ramp launching; the jib head sloop rig (low center of effort for stability) carries 200 square feet of sail (SA/D ~20 for lively acceleration, hull speed ~5.8 knots with 6–8 knots reaching in 10–15 knots breeze) on a tabernacle-stepped aluminum mast for effortless setup. Built via sheet plywood construction (¼-inch marine ply over oak frames, sheathed in fiberglass/epoxy for durability; 600–900 build hours using full-size patterns), the design features a self-bailing cockpit (6'3" long for starlit sleeping), and a surprisingly spacious cabin with full sitting headroom (5'6"), full-length berths for four adults, port/starboard galley provisions, portable head, and minimal centerboard trunk intrusion—ideal for couples or families.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. 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. You should take the same precautions, especially when the data is not from Sailrite. The information on this site is not guaranteed to be accurate.
