B&R rig with aft-swept spreaders and no backstay; large-roach main, vang trim important. Fin with bulb and spade rudder, 4.5 ft (sailboatdata); owners mention a less weatherly keel version and a deeper fin. Two mainsheet layouts: cabintop traveler or short pedestal-mounted traveler. Two interior layouts, one with a separate V-berth. Owners say engine access is good. Sailboatdata lists no last-built year. Hull laminate not stated in sources read.

Engines & parts

Yanmar 3GM / 3GM30F parts: good

Factory standard engine — you entered “Yanmar 3GM30F”

Very popular (used 3GM30Fs sell for $3,000+) and supported by a strong parts network. Cylinder head overhauls (valve seals, lapping, injector service) are a common, parts-supported repair.

Parts sources: Mack Boring & Parts (Yanmar distributor), HDI Marine (stainless exhaust elbows), Parts4Engines

Common problems (2)
  • Overheating at cruise rpm cooling
    The 3GM30F has a known overheating tendency linked to its heat exchanger; owners also trace it to coked elbows, worn impellers, scaled heat exchangers or air in the raw water circuit. Some heat exchangers were replaced under warranty.

  • Mixing elbow corrosion exhaust
    OEM elbows corrode internally and should be inspected or replaced with stainless versions before they let water into the engine.
