About the Com Pac 33

Built by Com-Pac Yachts, this 33-foot sailboat represents the builder's venture into larger cruising vessels, expanding beyond their well-established lineup of smaller coastal cruisers. Com-Pac earned a solid reputation for constructing sturdy, traditional sailing yachts that prioritize comfort and seaworthiness over racing performance. The Com Pac 33 follows the company's design philosophy of creating boats suited for serious coastal cruising and light offshore passages. Like other Com-Pac models, this vessel likely features a full keel configuration that provides excellent tracking and stability in various sea conditions, though at some cost to maneuverability in tight quarters. This sailboat appeals to sailors seeking a comfortable platform for extended cruising adventures, with accommodations designed for living aboard during extended passages or seasonal cruising. The Com-Pac 33's construction emphasizes durability and traditional sailing characteristics rather than cutting-edge performance, making it suitable for cruising couples or small families who value reliability over speed. While detailed specifications remain limited, the boat's size and Com-Pac's design heritage suggest it offers a good balance of interior volume and sailing capability, making it an interesting option for sailors considering a step up to serious coastal and offshore cruising.

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
18.5
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
21.08
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
2.13
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.
Under 3.0 — Slow cruiser3.0–5.0 — Average cruiser5.0–7.0 — Performance cruiserOver 7.0 — Racer
