About the Bianca 101

With limited specifications publicly available, the Bianca 101 represents one of the more elusive entries in the sailing world's catalog of production boats. This scarcity of detailed information often indicates either a limited production run or a regional manufacturer with focused distribution channels. Based on the numerical designation suggesting a roughly 10-meter length overall, the Bianca 101 would typically fall into the category of mid-sized sailing yachts suitable for both coastal cruising and potentially light offshore passages. Boats in this size range generally offer a practical balance between manageable sailing characteristics for smaller crews and sufficient interior volume for extended cruising comfort. The Bianca name, while not immediately recognizable among mainstream production builders, suggests European origins where many specialized sailboat manufacturers have created quality vessels for discerning sailors who prefer boats outside the mass-market offerings. These manufacturers often focus on traditional construction methods, quality materials, and thoughtful design details that may not appear in specification sheets but contribute significantly to the sailing experience. For prospective buyers researching the Bianca 101, connecting with existing owners or regional dealers would provide the most reliable insights into this boat's sailing characteristics, construction quality, and overall suitability for intended use.

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
20.79
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
21.59
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
1.73
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. 6.87
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
3.85
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. 740.97
