About the Pearson 365 Ketch

Built during Pearson's heyday in the 1970s, this 36-foot ketch represents the yard's commitment to solid fiberglass construction and practical cruising design. The dual-masted ketch rig offers excellent sail handling flexibility, making it particularly appealing to shorthanded crews and those planning extended coastal passages. Pearson's reputation for building sturdy, seaworthy vessels is well-reflected in the 365's construction. The boat features the company's characteristic hand-laid fiberglass hull with substantial layup schedules that have proven their durability over decades. Her traditional lines and moderate proportions suggest a design prioritizing comfort and stability over pure performance. The ketch configuration provides several advantages for cruising sailors, including easier sail handling in heavy weather and the ability to balance the boat under various sail combinations. This makes the 365 well-suited for coastal cruising and offshore passages where reliability trumps speed. While detailed specifications remain limited, the boat's size and era place it squarely in the category of serious cruising vessels designed when Pearson was building some of its most respected models. Owners typically praise the boat's solid feel and seaworthiness, making it a compelling choice for those seeking proven offshore capability.

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
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
14.5
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
33.44
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
1.76
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. 7.34
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
1.39
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 1.0
