About the Dufour 4800

French shipbuilder Dufour Yachts positioned this 48-footer as a sophisticated cruising yacht designed to bridge performance and comfort for discerning sailors. Part of Dufour's modern lineup, the 4800 represents the builder's commitment to creating vessels that excel in both coastal and offshore sailing scenarios. Built with Dufour's characteristic attention to seaworthiness and sailing dynamics, this model features contemporary naval architecture that prioritizes both speed under sail and stability in varied conditions. The design philosophy emphasizes creating a yacht capable of handling extended passages while providing the refined accommodations expected by today's cruising sailors. The 4800 incorporates modern construction techniques and materials, reflecting Dufour's evolution toward lighter, stiffer hulls that enhance performance without sacrificing the robust build quality the French yard is known for. The cockpit layout and deck hardware are engineered for efficient sailing, whether single-handing or with crew. This model appeals to sailors seeking a yacht that can transition seamlessly from weekend coastal sailing to longer offshore adventures. The 4800's design strikes a balance between the performance characteristics desired by experienced sailors and the comfort features necessary for extended cruising, making it suitable for couples or small groups planning ambitious sailing itineraries.

Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
15.3
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
25.35
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
1.94
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. 7.03
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
