About the Mumm 36

Designed by Bruce Farr and first launched in 1993, this French-bred performance cruiser represents a successful balance between racing capability and comfortable coastal sailing. With 120 hulls built under license by Carroll Marine, the Mumm 36 carved out a respected niche in the competitive 36-foot market during the 1990s. The boat's composite construction and modern underbody featuring a fin keel with bulb and spade rudder configuration deliver impressive sailing performance. Her fractional sloop rig and generous sail area of 644 square feet provide excellent light-air performance, while the relatively deep 7.33-foot draft ensures good windward ability. The SA/Displacement ratio of 25.53 confirms this is a boat that rewards skilled helmsmanship with spirited performance. At 8,150 pounds displacement with 3,500 pounds of ballast, the Mumm 36 offers reasonable stability for coastal cruising and club racing. The low comfort ratio of 14.22 reflects her performance-oriented nature rather than cruising luxury, while the capsize screening value of 2.36 suggests she's best suited for protected waters and coastal sailing rather than extended offshore passages. Her 18-horsepower auxiliary provides adequate auxiliary power for maneuvering in tight quarters.

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
 45
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
 25.53
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
 42.94
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
 113.68
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
 14.22
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
 2.36
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. 7.55 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
 5.24
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. 1,342.07 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. 25.53
