Operation Manual Operation
Before using the system, practice manual operation in case there is a loss of power. Make sure that the emergency
handle can rotate and not hit the bow pulpit.
Cordless drill adapters work well, but there must be a fully-charged cordless drill on hand at all times. Because
a cordless drill may lose power, always have an emergency handle onboard in a secure, easy-to-find location.
Communicate location as part of safety equipment orientation for all crewmembers.

harness and tether, go forward.
