Document Summary
Yaw = like the wobbles on a skateboard, inability to stay going in one direc5on. Broach = heading suddenly changes towards the wind due to wind/sail interac5ons for which the rudder cannot compensate. This causes the boat to enter a death roll. Pitch pole = the vessel starts to go down a wave so fast, tons of damage, people usually die. Lod (length on deck) = from the stem all the way to the stern. Loa (length overall) = maximum length of hull parallel to water line. Greatest stress on the hull is the curved part and the middle point. *dra% = keel to water line, or actual water line; can change how much cargo is aboard or salt vs fresh water. Theore5cal hull speed = displacement speed is the speed at which the wavelength of the boat"s bow wave (in displacement mode) is equal to the boat length. 1 knot = 1. 15 mph = 6,076.
