Prelude 12
Description
The Prelude 12 by Northwest Marine Design (associated with naval architect A.C. Gondola, N.A., operating out of the Seattle/Poulsbo, WA area under Northwest Marine Design) is a small, nimble sailing dinghy designed as a responsive daysailer emphasizing easy handling, quick performance, and suitability for day sailing, club racing, beginner instruction, or teaching young sailors on lakes, protected bays, or inshore waters. It appears to be a lesser-known or limited-production/custom design from the late 20th/early 21st century era (with ties to plywood construction methods common in Northwest home-building scenes), featuring a simple Bermuda sloop rig for forgiving and lively sailing, likely lightweight build (possibly plywood or similar for trailering and low cost), shallow draft via centerboard or daggerboard for beaching/easy launch, and a focus on fun, stable handling without complex features—no large-scale builder or tracked production quantity is documented, suggesting amateur/home builds or small-shop examples rather than series production. A.C. Gondola is credited with various small craft designs through Northwest Marine Design (e.g., K-series like K-19, K-23 daysailers/cruisers in plywood/glass options), and the Prelude 12 fits this portfolio of accessible, practical sailboats.
