Design and Construction
The hull is solid fiberglass with a solid fiberglass deck, and the keel is lead on a fin profile with the rudder carried on a skeg. Her 12.25-foot beam and 6.3-foot draft place her squarely in the moderate-displacement tradition, with 17,800 pounds of displacement and 9,200 pounds of ballast — a 51.69 percent ballast-to-displacement ratio that gives her a capsize screening value of 1.88 and a comfort ratio of 27.48. What distinguishes the 43 from her later 41 sibling is the extended "traditional" counter aft, which accounts for her greater length from the same basic mold set anchor. The displacement-to-length ratio of 233.63 and a sail-area-to-displacement ratio of 18.26 describe a boat built for loaded cruising rather than all-out speed, with a theoretical hull speed of 7.63 knots.
Rig and Handling
As a masthead sloop, the Tartan 43 carries a total sail area of 778 square feet under a rig with an I measurement of 16.46 meters and a J measurement of 5.26 meters. The foretriangle drives a genoa of 43.29 square meters, while the mainsail spans 28.81 square meters on a 14.55-meter P and 3.96-meter E. Her fin-and-skeg configuration and moderate beam suggest predictable helm behavior in a seaway, and the heavy displacement indicates a hull that sits firmly when loaded — a trait consistent with her comfort-oriented design numbers rather than a lightweight planing hull.
Accommodations
The Tartan 43 provides a 13.11-meter LOA and 3.73-meter beam platform from Sparkman & Stephens, and the extended counter aft implies a longer waterline profile than the 41 that followed from the same tooling.
Known Issues
The Tartan 43 shows no structural defects, osmotic problems, or systemic rigging failures in her service history. The 1973 production run and the boat's status as the precursor to the Tartan 41 mean that surviving examples are few.
Refits and Ownership
Ownership of a Tartan 43 places the keeper in a small cohort of caretakers for a one-year-only design. The boat shares DNA with the Tartan 41, which eased spares and knowledge transfer across the two models, but the 43's unique counter and 1973 build make her a distinct collector's proposition rather than a mainstream production cruiser.
The Verdict
The Tartan 43 is a quietly significant hull — the precursor that proved the tooling later popularized by the Tartan 41, wrapped in a longer traditional counter and finished to early-1970s Tartan standards. She is a boat for the owner who values lineage and moderation over volume production.
Pros
- Sparkman & Stephens design with lead fin keel and skeg rudder
- Heavy ballast ratio (51.69%) and reassuring capsize screen (1.88)
- Direct structural link to the proven Tartan 41 tooling
Cons
- Single-year 1973 production limits spares commonality and fleet support
- Accommodation and systems detail not described in available references
- Moderate sail-area-to-displacement ratio favors loaded cruising over pace
