About the Avance 33

With limited specifications available, the Avance 33 represents a somewhat elusive entry in the 33-foot sailing yacht category. This vessel appears to be part of the broader European sailing tradition, though detailed information about its design lineage and construction remains scarce in readily accessible maritime databases. Based on its nomenclature and typical characteristics of similarly sized vessels from this era, the Avance 33 likely falls into the coastal cruising category, designed for weekend adventures and short-term coastal passages rather than extended offshore voyaging. The 33-foot length suggests a boat that balances reasonable accommodation below with manageable handling characteristics for small crews or couples. Without comprehensive specification data, potential buyers should focus their research on locating original brochures, surveyor reports, or connecting with existing owners through sailing forums and yacht clubs. The relative obscurity of detailed specifications may indicate either limited production numbers or regional distribution, which could affect both parts availability and resale value. For sailors considering this vessel, thorough professional survey and inspection become even more critical given the limited published information available to guide purchase decisions.

Performance Ratios
PHRF Rating PHRF (Performance Handicap Racing Fleet) is a national racing handicap measured in seconds per nautical mile. Lower values indicate faster boats. Ratings are sourced from US Sailing's national database (median across 60+ regional fleets).
Under 0 — Ultralight racer0–90 — Performance racer90–150 — Cruiser/racer150–210 — Typical cruiserOver 210 — Heavy/slow cruiser
153
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
17.64
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
25.96
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
1.7
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. 6.99
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
