About the Farr 30 Mumm 30

Designed by renowned naval architect Bruce Farr in 1995, this 30-footer emerged during the height of the one-design racing boom as part of the Mumm series. Built by multiple manufacturers including Carrol Marine, Mcdell Marine, and Ovington Boats, the design reflects Farr's mastery of creating fast, competitive sailboats that balance performance with manageability. The hull configuration features a modern fin keel with bulb and spade rudder arrangement, delivering excellent upwind performance and responsive handling. With a sail area to displacement ratio of 29.4 and fractional sloop rig carrying 504 square feet of sail, this boat rewards skilled sailors with impressive speed potential. The relatively light 4,561-pound displacement and aggressive 43.8% ballast ratio contribute to spirited performance characteristics. While designed primarily for one-design racing and club competition, the Farr 30's seaworthy design makes it capable of coastal cruising and offshore passages in experienced hands. The low comfort ratio of 11.33 indicates this is fundamentally a performance-oriented vessel rather than a cruising boat. The capsize screening formula of 2.44 suggests reasonable stability for experienced sailors, though the design clearly prioritizes speed over ultimate stability. This boat appeals to racing enthusiasts seeking competitive performance in a manageable 30-foot package.

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
 29.4
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
 43.78
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
 96.85
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
 11.33
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
 2.44
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. 7.04 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
 6.19
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. 996.04 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. 29.4
