What is Broaching-to?

Broaching-to is a sudden movement in navigation, when the ship, while scudding before the wind, accidentally turns her leeward side to windward. The term is also used to describe the point when water starts to come over the gunwhale due to this turn.

Broaching-to phenomena occurs when operating in following seas and when the speed of the waves is the same or faster than the ship's speed. It often results in a ship losing steerage when it is being accelerated forwards on the steep forefront of a high wave, which is then followed by surf-riding.
