Design and Construction

The hull is solid fiberglass below the waterline, while the teak deck sits over a fiberglass-and-plywood sandwich anchor. Ron Holland's 1980 version differs from the earlier Ron Amy 43 sold as Spindrift and Hampton. The 37 percent ballast ratio gives below-average heel resistance, and the 1.73 capsize screen would admit ocean racing by that formula alone.

Rig and Handling

Her masthead rig shows a sail-area-to-displacement ratio of 15.43. The wetted surface is about 516 square feet and immersion 1,836 pounds per inch. Jib and genoa sheets run 41.8 feet at 14 mm, mainsheet 104.6 feet, spinnaker sheet 92 feet. The length-to-beam ratio is 3.32 and she is roomier than half of similar designs.

Accommodations

Below, she has three cabins, a galley, and a toilet, all in teak. The 120-gallon water and 60-gallon fuel support cruising; the 33.33-foot waterline gives three cabins room.

Known Issues

The teak-over-plywood deck is a water-ingress path if caulking fails; the solid hull below avoids core rot but shows grounding damage plainly.

Refits and Ownership

Owners face teak renewal and rigging replacement given 14 mm sheets and 1980 start. The Volvo Penta MD 21A of 60 horsepower drives one shaft; 60-gallon tankage warrants re-plumb. Only 20 built limits spares.

The Verdict

A heavy, beamy, teak cruiser balancing formula ocean-race admissibility against below-average heel resistance.

Pros

  • Solid glass hull below waterline, no core rot
  • Three teak cabins, 120-gallon water
  • Capsize screen 1.73 admits ocean racing by formula

Cons

  • Teak deck over plywood invites ingress
  • Ballast ratio resists heeling below average
  • Only 20 built, thin spares market
