Design and Construction
Amy’s hull measures 42.5 feet overall, with a 35.58-foot waterline, a 12.96-foot beam, and a displacement of 34,810 pounds. She carries 10,043 pounds of iron ballast. Her length-to-beam ratio of 3.33 and displacement-to-length ratio of 333 place her firmly among heavy cruisers.
Ka Shing built the boat in fiberglass with a long keel. The wetted surface is about 516 square feet, while an immersion rate of 1,621 pounds per inch indicates how reluctant she is to squat under load—a useful trait for a boat fitted out for long passages rather than tuned for regattas.
A capsize screening value of 1.58 and a motion comfort ratio of 46.4 describe a stable, forgiving platform. Elsewhere, her comfort ratio is given as 47.12, likewise suggesting a settled motion at sea.
Rig, Sail Plan, and Handling
The cutter rig carries a 1,141-square-foot sail plan. The foretriangle has an I dimension of 53.92 feet and a J of 17.75 feet, while the mainsail hoist (P) is 49.50 feet.
Sheet specifications are generous: jib and genoa sheets are 43 feet long and 5/8-inch in diameter, the mainsheet is 107.5 feet, and the spinnaker sheets are 94.6 feet. All are sized for secure control of the sail plan.
With a sail-area-to-displacement ratio of 17.12, the Spindrift combines sail power with easy handling, producing effortless speed rather than sparkling acceleration. Her theoretical displacement-hull speed is 8.0 knots; the standard formula gives 7.99 knots. She is built to maintain a steady offshore stride, and the cutter layout and heavy ballast provide the stiffness and directional steadiness that define the type.
Accommodations and Cruising Capacity
Three-cabin and alternative owner layouts appeared across the fleet, and some examples saw charter service. Tankage is substantial: 300 gallons of water and 250 gallons of diesel support extended cruising. Together with the boat’s interior volume, that capacity marks the Spindrift 43 as a boat intended for weeks aboard rather than weekend hops.
Verdict
The Spindrift 43 is a quintessential early-1980s heavy cruiser. Ron Amy’s lines, Ka Shing’s Taiwanese fiberglass construction, and a long-keel hull all favor seaworthiness over agility. This is a boat to judge by its steadiness, tankage, and the quiet confidence of a roughly 34,000-pound hull—not by its light-air sprinting ability.
Pros
- Sturdy, seaworthy heavy-displacement cutter built by Ka Shing beginning in 1982
- Ballast ratio near 29 percent, a 1.58 capsize screening value, and comfort ratios of 46.4 and 47.12
- Generous capacity of 250 gallons of diesel and 300 gallons of water for long-range cruising
- Cutter rig with full-size sheet specifications suited to offshore control
Cons
- Heavy-cruiser proportions limit light-air responsiveness
- Draft of 6.33–6.63 feet restricts her to major marinas
