About the S2 103

Produced by S2 Yachts during the brand's prolific run of quality American-built sailboats, the S2 10.3 earned a reputation as a capable and well-balanced cruiser-racer that appeals to sailors seeking versatility without compromise. S2 Yachts, founded by Leon Slikkers, was known for meticulous construction standards and thoughtful design, and the 10.3 reflects that heritage in its refined hull form and purposeful layout. Suited to coastal cruising and buoy racing alike, this boat offers enough performance to satisfy competitive sailors while providing the comfort and predictability that weekend cruisers demand. Its hull design rewards attentive helmsmanship and is said to handle a range of wind conditions with confidence, making it a practical choice for sailors in variable coastal environments. The 10.3 tends to attract buyers who appreciate a boat that doesn't demand constant attention or expensive upkeep, thanks to the solid build quality that S2 became known for throughout its production years. For those exploring the used market, examples of this model are generally regarded as solid values, offering a well-rounded sailing experience backed by a respected American boatbuilding legacy.

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
18.88
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
21.53
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
2.07
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. 7.09
S# (Speed Number) The Speed Number (S#) is a quick performance index. Higher values indicate a faster, more powerful design relative to its size.
