Glen-L Feather

Description

The Glen-L Feather is an 11-foot fiberglass sloop designed by Glen L. Witt, founder of Glen-L Marine, as an accessible "first project" for amateur builders using the innovative C-Flex planking method—where narrow fiberglass strips are overlapped, stapled to a temporary framework, and laminated in place, allowing most form members to be removed post-construction for a seamless, molded-like hull that's lightweight (around 200-250 pounds) and surprisingly durable. With a sleek round-bilge shape, 5'2" beam, 6" draft (daggerboard up), and a generous 110-square-foot Bermuda sloop rig, it delivers sprightly performance for daysailing, solo or with a crew of two, while its watertight flotation compartments render it unsinkable—a key feature praised by builders for family-friendly stability over "tippy" alternatives like classic Moths. Plans include full-size patterns, detailed instructions, and options for woodstrip construction or basic outboard powering; it's trailerable, rowable as a backup, and remains popular among homebuilders for its forgiving build process and elegant simplicity, with completed examples often mistaken for production boats.

Custom sail calculations are not possible for this boat as no I, J, P and E dimensions are available.

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.
