3 B/D - 40%
4 D/L - 287
5 motion of comfort - 34
6 Capsize screen
any help would be great
Not knowing the exact context from which you extracted these figures, I can only offer the following:
1 - PHRF = Performance Handicap Racing
Fleet - a system of using handicap performance formulae to "adjust" the racing
times of dissimilar vessels. Think of the practice of placing weight in the saddles of thoroughbred horses to compensate for previous experience and race
2 - SA/D = Sail Area/Displacement - the ratio of the total area of a vessel's sails
to the weight of the water
displaced by its hull(s).
3 - B/D = Don't know what the B refers to, for certain, though I suspect it might be ballast, but the D is, again, displacement
4 - D/L = Displacement/Length - the ratio of the weight of the displaced water
to the vessel's length (probably LWL, or Load Water Line).
5 - Not familiar with this term.
6 - Probably a formula for determining at what point a vessel turns turtle (capsizes) instead of coming back onto her feet (regains an upright position), or as rebel heart puts it, has "the stick in the air."
I could be wrong on the above, and others with greater knowledge will correct me, but thought I'd try to help.
