Question 5093 Deck General

The correct answer is A) jack the vessel back up to a safe height. The reasoning is that a flooded leg on a liftboat can lead to a dangerous list that compromises the stability and safety of the vessel. The immediate priority should be to jack the vessel back up to a safe height to restore stability and prevent further flooding or potential capsizing. Options B and C are incorrect because the list is a serious issue that needs to be addressed promptly, not ignored or reported to the Coast Guard without first taking steps to stabilize the vessel. Option D is also incorrect, as pumping out ballast would not address the root cause of the flooded leg and could further destabilize the liftboat.
