Guppy 9
Description
The Guppy (full name Guppy 9) by Sam Devlin is a charming, versatile stitch-and-glue plywood dinghy/skiff/small sailboat designed by the renowned American naval architect Sam Devlin of Devlin Designing Boat Builders (based in Olympia, Washington). Introduced as a slightly larger "cousin" to Devlin's popular Polliwog rowing dinghy, the Guppy 9 adds sailing capability while retaining excellent rowing and motoring traits—making it an ideal all-around tender, daysailer, or first boat for amateur builders, kids, beginners, or anyone seeking a lightweight, low-maintenance pocket craft for protected waters like lakes, bays, or rivers. It's praised for its forgiving nature ("without vice"), efficient performance, good carrying capacity, and straightforward construction using marine plywood, epoxy, and fiberglass tape—perfect for modest shop space and first-time builders.
