## Sail Area Calculations
The following formulas are approximate Sail areas depend on lots of factors, leach hollow, foot round, luff hollow etc. Also, remember that jib sail area in general is based on the forestay length, I. But all things considered, these numbers are close but should not be considered exact. They are rules of thumb, not measurements of a this specific boat. ## MainsailMainsail = (P x E) / 2 = 207 sq ftRacing Mainsail (add 10%) = 228 sq ft ## Genoa155% Genoa = (( J x I ) / 2) x 1.65 = 470 sq ft135% Genoa = (( J x I ) / 2) x 1.44 = 410 sq ft ## Jib
100% Jib = ( I x J ) / 2 = 285 sq ft A more accurate LP calculator is HERE ## SpinnakerSpinnaker Area = Max Luff x Max Girth x ( 70-85%) = 734 to 891 sq ft"Square" Spinnaker Area = Max Luff x Max Girth) = 1048 sq ft AC Area = 873 sq ft Maximum Luff (.95 * sqrt (JSP^2 + ISP^2) = 38.81 feet Maximum Girth = 1.8 * JSP = 27 feet Ref ## DEFINITIONS"P" is the luff length of the mainsail, measured along
the aft face of the mast from the top of the boom to the highest point
that the mainsail can be hoisted or black band.
