About the Oyster 42

Built by the renowned British yard Oyster Marine, the 42 is a thoroughbred blue-water cruiser designed to carry her owners safely and comfortably across oceans. Oyster has long held a reputation for producing some of the world's most trusted offshore sailboats, and the 42 upholds that legacy with a hull and construction philosophy focused on seakeeping, structural integrity, and long-distance capability. Suited to serious offshore passagemaking as well as extended coastal cruising, this boat appeals to sailors who demand reliability in demanding conditions without sacrificing comfort below decks. Oyster's hallmark attention to interior finish and live-aboard liveability is evident throughout, making extended time at sea genuinely enjoyable rather than merely functional. The 42 sits at an accessible size within the Oyster range, offering enough volume for comfortable blue-water passages while remaining manageable for a shorthanded crew or a couple sailing together. For those researching a boat that balances genuine offshore performance with the build quality and brand confidence that Oyster consistently delivers, the 42 represents a compelling option worth investigating closely.

Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
 132
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
 18.15
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
 37.99
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
 1.72
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. 7.78
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
