Q

Plowing mode

A

As speed increases, a planing hull will have a raised bow, reducing the operator’s vision and throwing a very large wake. Avoid maintaining a speed that puts your boat in plowing mode.

Planing mode

A

Your boat is in planing mode when enough power is applied so that the hull glides on top of the water. Different boats reach planing mode at different speeds.
