Performance Calculations
PHRF (base with Scheel keel):
High-135 (PHRF-NE BASE HANDICAPS 31 March 2011);
Low-147 (US Sailing);
Average-141 (US Sailing).
Maximum Hull Speed: 7.19 kts. (can be bettered on reach)
Capsize Screening Formula (CSF): 1.97 (good if <2)
Sail Area/Displacement (SA/D): 17.40 (Cruiser-Racer)
Displacement/Length (D/L): 204.93 (Moderate Disp. - Cruiser/Racer)
Motion Comfort Ratio: 21.41 (Low offshore, good coastal cruising)
Ballast/Displacement (B/D): 40% (very good)
Beam/LOA: 31.40 (Good directional stability)
Cutlass Bearing size: 1 inch ID, 1.5 inch OD, 4 inches long

The performance calculations are theoretical and calculated from manufacturer's specifications.
