Nearly 1,000 built across both versions. The original has a swept scimitar keel and rudder (4.5 ft draft); the 28 II (from 1982) has a higher-aspect fin of 5 ft 2 in and a spade rudder, with a 4 ft shoal keel optional. Specs shown are the original 28; sailboatdata lists it 1974-81 and the 28-2 from 1982. Most early boats have the Atomic 4 gas engine; later boats had Universal or Yanmar diesels. Deck is balsa-cored. Water tank size not found. Good Old Boat describes the hull as solid glass. Build count given only as approximate: "almost 1,000" (Practical Sailor), "nearly 1,000" (Good Old Boat), "more than 1000" including the 28-2 (sailboatdata).

Engines & parts

Universal Atomic 4 parts: good

Factory standard engine — you entered “Universal Atomic 4”

Tens of thousands were built (sources say from 40,000 to 50,000). Despite being out of production for decades, the engine is well supported: Moyer Marine sells parts, rebuilt engines, fuel pump rebuilds and exhaust parts, and hosts an owners' forum; Old Lyme Marina and others also supply parts, and electronic ignition upgrades are available.

Common problems (3)
  • Raw-water cooling scale and corrosion cooling
    Most Atomic 4s are raw-water cooled, so the block scales up and corrodes, especially in salt water; cranking without starting can also flood the engine with seawater through the exhaust.

  • Gasoline vapor fire/explosion risk fuel
    Gasoline vapor is heavier than air and settles in the bilge, so ventilation, blower use and shutting the fuel valve (a stuck carburetor float can overflow) matter.

  • Ignition and fuel system faults electrical
    Points, condenser, cap and wires, plus gummed carburetors and contaminated fuel, are the most common reasons an Atomic 4 won't run well.
