With conservative, seakindly proportions, a masthead sloop rig, and a lead-ballasted fin keel with a skeg-hung rudder, the Tartan 43 reflects the American cruiser-racer tradition of the early 1970s.
Design and Construction
The Tartan 43 measures 43 feet overall, or 13.11 meters, with a 32.4-foot waterline, a beam of 12.25 feet, or 3.73 meters, and a draft of 6.3 feet. Sparkman & Stephens designed the solid-fiberglass hull and solid-fiberglass deck. The keel is lead on a fin profile, while the rudder is carried on a skeg.
Displacement is 17,800 pounds, including 9,200 pounds of ballast. That produces a ballast-to-displacement ratio of 51.69 percent, a capsize screening value of 1.88, and a comfort ratio of 27.48. Together with the boat’s moderate beam and draft, these figures place it squarely in the moderate-displacement tradition.
A displacement-to-length ratio of 233.63 and a sail-area-to-displacement ratio of 18.26 describe a boat intended for loaded cruising rather than all-out speed. Its theoretical hull speed is 7.63 knots.
Rig and Handling
The masthead sloop rig carries 778 square feet of total sail area. The I measurement is 16.46 meters and J is 5.26 meters. The foretriangle carries a 43.29-square-meter genoa, while the mainsail measures 28.81 square meters, with a P measurement of 14.55 meters and an E measurement of 3.96 meters.
The fin-and-skeg configuration and moderate beam suggest predictable helm behavior in a seaway. The heavy displacement also indicates a hull that sits firmly when loaded, in keeping with its comfort-oriented design numbers rather than those of a lightweight planing hull.
Accommodations
Available references don’t describe the Tartan 43’s accommodation plan or systems in detail. Its basic platform provides a 13.11-meter LOA and 3.73-meter beam. The extended counter aft implies a longer waterline profile than that of the Tartan 41, which followed from the same tooling.
Known Issues
The Tartan 43 shows no structural defects, osmotic problems, or systemic rigging failures in its service history. Its single 1973 production run, and its status as the precursor to the Tartan 41, mean that few examples survive.
Refits and Ownership
A Tartan 43 owner joins a small group of caretakers for a one-year-only design. The boat shares DNA with the Tartan 41, which eased spares and knowledge transfer between the two models. Even so, the 43’s unique counter and 1973 build make it more of a distinct collector’s proposition than a mainstream production cruiser.
The Verdict
The Tartan 43 is a quietly significant design: the precursor that proved the tooling later popularized by the Tartan 41, but with a longer traditional counter and an early-1970s Tartan finish. It suits an owner who values lineage and moderation over volume production.
Pros
- Sparkman & Stephens design with a lead fin keel and skeg-hung rudder
- High ballast ratio of 51.69 percent and a reassuring capsize screening value of 1.88
- Direct structural link to the proven Tartan 41 tooling
Cons
- Single-year 1973 production limits spares commonality and fleet support
- Available references don’t describe the accommodations and systems in detail
- Moderate sail-area-to-displacement ratio favors loaded cruising over pace
