Not just because of wave action....
"Broaching" is used to define a vessel turning sideways (normally quite suddenly and violently) , not just because of sea conditions but actually through any external force.
ie: "the motor cruiser broached as a result of a collision with another vessel"
Or " The tugboat braoched due to excessive loads on its tow wire"
