Bill,
Quick question on your throttle control setup.  Using a Morse throttle cable to control the Sevcon throttle; how do you achieve a throttle "lock" in neutral to prevent the electric motor from powering up if someone accidentally bumps the throttle lever, or a line should snag on it and power it up?  That would be a serious concern for me.

I have a separate switch that turns off the controller. Once it's off the position of the throttle no longer as any affect. Also a very visible 'E-stop' button that like wise cuts power (by disconnecting the main power contactor coil so every thing in the motor control chain gets disconnected from the battery supply).
