The correct answer is A) the davits should always be hand cranked the last 12 inches into the final stowed position. This is correct because when operating gravity davits, the final positioning of the davits into the stowed position should be done manually to ensure a controlled and safe stowage. Allowing the davits to freefall the last 12 inches can lead to damage or injury. Regulations require the final positioning to be done by hand cranking for a smooth and secure stowage. The other answer choices are incorrect because: B) tripping the tricing pendant is not necessary before releasing the gripes, C) the gripes should be released before the boat is moving, and D) gravity davits are not typically lowered by surging the falls around bitts.
