tom kane: Pivotal drive with Emergency brake reverse bucket.
A drive run in surface piercing mode. Surface Drive with a Kort Nozzle and an Emergency brake twin rudders and reverse bucket can stop you quick and give more control. Works similar to a Kitchen Rudder and turn in a boat length at low speed. When lifted to surface piercing mode there is a lot less metal in the water and less drag.
