About the Pacific Seacraft 31

Built by Pacific Seacraft during the company's renowned era of traditional cruising yacht construction, this 31-footer exemplifies the builder's commitment to offshore-capable vessels designed for serious coastal and blue water sailing. Pacific Seacraft earned a stellar reputation among cruising sailors for producing heavily built, seaworthy boats that prioritized safety and comfort over speed. The Pacific Seacraft 31 carries the hallmark characteristics that made the yard famous: full keel configuration for directional stability, robust fiberglass construction, and thoughtful interior layouts optimized for extended cruising. These boats typically feature quality joinery work and attention to detail that reflects the builder's focus on creating vessels capable of handling challenging offshore conditions. Known for their ability to track well in heavy weather and maintain course with minimal helm input, Pacific Seacraft designs appeal to sailors who value seaworthiness over performance racing characteristics. The 31 represents an ideal size for couples or small families seeking a capable cruiser that remains manageable for shorthanded sailing while offering sufficient space and storage for extended voyaging. This model continues the Pacific Seacraft tradition of building boats that inspire confidence in their owners, whether coastal cruising or crossing oceans.

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.

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
15.81
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
30.6
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
1.77
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. 6.59
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
