Headsails “Set Flying” aerodynamic coefficients (calculation)
A headsail is a sail set forward of the mast. Headsails may be set on the forestay or set flying, i.e., with no sail edge attached to the forestay. Wi…
Genoa aerodynamic coefficients (calculation)
A headsail is a sail set forward of the mast, or of the foremast mast if there is more than one mast, where the measurement between the half luff poin…
Jib aerodynamic coefficients (calculation)
A headsail is a sail set forward of the mast, or of the foremast mast if there is more than one mast, where the measurement between the half luff poin…
Mainsail aerodynamic coefficients (calculation)
A mainsail is a sail with the luff attached to the mainmast. The mainmast is the only mast in a una rig, sloop rig, or cutter rig, the fore mast in a …
