About the Oe 33

Designed by Swedish naval architect Olle Enderlein, this rare 33-footer represents a thoughtful approach to coastal cruising from the late 1970s. With only 20 hulls produced by Crown Marine between 1977 and 1981, the Oe 33 has become something of a collector's piece among enthusiasts of European design philosophy. The boat's proportions reveal a design optimized for comfortable passage-making rather than pure racing performance. Her generous beam of 9 feet provides excellent interior volume and stability, while the moderate draft of just over 5 feet opens up more cruising grounds than deeper-keeled contemporaries. The fin keel with rudder on skeg configuration offers a good balance of performance and directional stability, particularly appreciated during longer passages. With a comfort ratio of 24.2, the Oe 33 falls into the moderate category that favors coastal and near-offshore cruising over extreme ocean passages. The capsize screening formula of 1.78 indicates reasonable stability characteristics for her intended role. Her fractional sloop rig with 441 square feet of sail area provides adequate power while remaining manageable for small crews. The fiberglass construction has proven durable over the decades, though potential buyers should pay particular attention to the quality of the original layup given the boat's age and limited production run.

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
 17.16
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
 44.75
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
 192.19
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
 24.2
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
 1.78
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. 6.95 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
 2.82
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. 865.05 pounds/inch
SA/Displacement (Calc) Calculated Sail Area to Displacement ratio using actual measured sail dimensions rather than reported values. More precise than the reported SA/Disp figure. 17.17
