Roberts 39
Description
The Bruce Roberts 39 is a classic heavy-displacement cruising cutter (or sloop/ketch) designed by Bruce Roberts-Goodson in the 1970s, renowned for its robust multi-chine hull providing exceptional seaworthiness and stability for bluewater passages or extended coastal voyages, with hundreds built worldwide as affordable DIY projects emphasizing luxury accommodations for a couple or small family. Featuring a full or long keel for directional stability and a generous beam for interior volume, it's optimized for steel or aluminum construction with options for short (5'9") or long (5'3") draft, delivering balanced performance under a powerful sail plan suitable for light to moderate winds, powered by a typical 30–40 hp diesel auxiliary; plans from bruceroberts.com include full-size patterns, engineering drawings, and over 50 photos, with build costs around $80,000–$150,000.
