About the Pj 34

Designed by the respected Swedish naval architect Peter Norlin, the PJ 34 is a performance-oriented sloop that earned a strong following in European sailing circles during its era. Norlin was known for producing fast, well-balanced designs with clean lines and responsive handling, and the PJ 34 reflects that philosophy throughout its construction and layout. Well-suited to both competitive club racing and spirited coastal cruising, this vessel appeals to sailors who want genuine performance without sacrificing practicality on longer passages. Its Scandinavian heritage suggests a hull built to handle challenging conditions, including the cold, choppy waters of the Baltic and North Sea, giving prospective buyers confidence in its seakeeping ability. While detailed specifications remain limited in available records, the PJ 34 has maintained a loyal community of owners who appreciate its sailing character and the quality of its engineering. For those researching a mid-size performance cruiser-racer with a credible pedigree, the PJ 34 is worth investigating further through owner forums, class associations, and hands-on inspection to fully appreciate what this capable Norlin design has to offer.

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
 12.49
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
 34.32
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. 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
