Sources disagree on first year, displacement, waterline — left blank rather than guessed.

Hull is partly balsa-cored (Baltek) with solid glass at the deck flange, through-hulls, chainplates and keel attachment, plus a vinylester skin coat and a five-year blister warranty. Deck is balsa-cored; hull-deck joint uses stainless fasteners tapped into aluminum plates molded into the hull flange. External keel on stainless bolts; 3-inch stainless rudder stock. Shoal 'beaver tail' keel option: 4.83 ft draft, 13,200 lb, 4,900 lb ballast. Sailing Magazine: 152 built, retired 2005; start year, displacement and LWL are disputed (see disputed). 25-gal aluminum fuel tank. Good engine access under the companionway.

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.
