Sail area is main area + 100% foretriangle area.
PHRF ratings vary from place to place. Ratings in your area may vary.
# is the Pearson model number for the design. See the serial number page for more info.
Hull Speed = SQRT(LWL)*1.34
SA/D = Sail Area Displacement Ratio = SA / (Disp/64)2/3
D/L = Displacement Length = (Disp/2240)/0.01*LWL)3
BR = Ballast Ratio = Ballast/Disp
L/B = Length/Beam Ratio = LOA/Beam
LWL/B = Waterline Length/Beam Ratio = LWL/Beam
LWL/BWL = Waterline Length/Waterline Beam Ratio = LWL/BWL
OR = Overhang Ratio = (LOA-LWL)/LOA
CSF = Capsize Screening Formula = Beam/((Disp/64.2)1/3
MCR = Motion Comfort Ratio = DISP / (.65*BEAM4/3(.7*LWL+.3*LOA))
M/F = Main/Foretriangle Ratio
