About the Cal 2 34

Designed by renowned naval architect C. William Lapworth, this classic 33-foot sloop represents the final evolution of Cal's popular mid-sized cruiser-racer series from the mid-1970s. Built by Jensen Marine for just two years between 1975-1976, only 198 hulls were produced, making this an increasingly rare find on today's market. The Cal 2 34 showcases Lapworth's signature approach to performance cruising, featuring a modern fin keel and spade rudder configuration that delivers responsive handling and respectable speed potential. With a hull speed of 6.83 knots and SA/Displacement ratio of 17.14, she offers a balanced blend of sailing performance and stability that appeals to both weekend cruisers and occasional racers. Her fiberglass construction and masthead sloop rig provide straightforward maintenance, while the moderate displacement of 9,500 pounds strikes an appealing balance between interior volume and sailing ability. The comfort ratio of 24.26 suggests she'll provide a reasonably comfortable motion at sea, though her relatively low capsize screening value of 1.89 indicates good stability characteristics for coastal and near-offshore sailing. This design works particularly well for sailors seeking a classic 1970s aesthetic combined with reliable performance for bay sailing, coastal cruising, and club racing activities.

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
 17.14
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
 39.47
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
 241.3
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
 24.26
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
 1.89
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. 6.83 kn
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
 2.27
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. 929.01 pounds/inch
