abrupt, involuntary change in a vessel’s course, towards the wind, resulting from loss of directional control, when the vessel’s rudder becomes ineffective
The best way to avoid broaching is to keep the boat sailing at a constant angle to the wind.
Good to know
Broaching refers to the loss of directional stability in waves caused by a large yaw moment that exceeds the rudders' ability to maintain course, potentially resulting in the vessel turning beam on to the waves and risking capsizing due to large roll moments.
