About the Buchan 37

Designed by Scottish naval architect Angus Primrose in the 1970s, this 37-foot yacht represents a notable example of British cruising boat design from that era. Built primarily in Scotland, the Buchan 37 emerged during a period when builders were focusing on creating robust, seaworthy vessels capable of handling challenging North Sea and Atlantic conditions. The design emphasizes traditional cruising qualities over pure performance, with a substantial build quality that reflects its Scottish heritage. Like many Primrose designs, the boat features a moderate displacement hull with good stability characteristics, making it well-suited for coastal and offshore cruising. The yacht's reputation centers around its seaworthiness and ability to handle rough weather conditions with confidence. While not designed as a racing yacht, the Buchan 37 offers respectable sailing performance under a variety of conditions. The interior layout typically prioritizes comfort and practicality for extended cruising, with adequate headroom and storage throughout. These boats have developed a following among sailors who appreciate solid construction and traditional sailing characteristics over modern performance-oriented features. Today, the Buchan 37 remains sought after by cruising sailors who value proven design principles and robust construction quality.

About this estimate
  • Prices are based on recent asking prices from public listings — not actual sale prices, which are typically lower.
  • Condition is not factored in. A well-maintained boat with new sails and engine can be worth significantly more than a project boat of the same model.
  • Location affects price. Boats in landlocked states or areas with fewer buyers often sell for less than those on the coast.
  • Year of manufacture is not filtered. Older examples of this model will generally be priced lower than newer ones.
  • Included equipment varies widely. A boat with a full suite of electronics, dodger, and new standing rigging may command a large premium.
  • Outliers are automatically excluded using statistical filtering to improve accuracy, but some bad data may remain.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
144
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
18.37
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
31.62
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
1.67
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 6.99
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
