Question 1330 Deck Safety

The correct answer is C) hand crank. The backup system on an electric start survival craft is a hand crank, which is used to manually start the engine in case the primary electric start system fails. This is a regulatory requirement specified in the US Coast Guard regulations for survival craft, as a redundant method to ensure the craft can be started in an emergency situation. The other options are incorrect because: A) a spare battery is not a backup system, it is simply a replacement for the primary battery; B) a pneumatic system is not typically used to start the engine in a survival craft; and D) a hydraulic system is not used to start the engine in this application.
