Wave spectral density (calculation)
The performance of a sailing boat is affected by the presence of surface waves. To understand the boat’s behavior under waves, it is necessary first…
Headsail 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 …
