Neptun 20
Description
The Neptun 20 is a compact, trailerable German micro-cruiser/daysailer built by Neptun Yachten GmbH (Neptun Boote GmbH & Co KG) in Germany, starting in 1973 (with production continuing into the 1980s or later based on surviving examples). Designer details are not widely attributed in public sources (often listed as unknown or in-house yard design by founders like Rudolf Eberhardt/Wolfgang Tiersch era), featuring a masthead sloop rig, fiberglass (GRP) construction with a centerboard (or twin keels/Kielschwerter in some variants) for shallow draft and beaching/drying out capability, plus a signature lifting roof (Hubdach) for increased headroom below (nearly standing height when raised). It's renowned for versatility in inland waters, coastal "buten" (outside) sailing, and family use—practical layout with 2–4 berths (including long berths in some), small galley/heads, outboard motor well (typically 4–6 hp), and easy trailering (often sold with trailer). Quantities built are not precisely documented but appear moderate for a regional classic (hundreds likely, given ongoing used market presence in Germany/Netherlands)
