Glen L 12
Description
The Glen-L 12, a spirited 12-foot stitch-and-glue plywood sailing/rowing pram designed by Glen L. Witt in the 1950s and offered through Glen-L Marine Designs, stands as one of the firm's most beloved junior trainers, tenders, and pocket adventurers—perfect for lakes, ponds, or sheltered bays where simplicity, portability, and pure fun converge. Measuring 12 feet LOA with a 5-foot beam and 6-inch draft (daggerboard up; 2'3" down), it displaces just 140 pounds (no ballast—crew weight provides stability), making it car-toppable, bike-towable, or stowable in a garage corner.

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.
