70% to pass

After jacking down your liftboat you have an unexpected list. You find that the only cause of this list must be a flooded leg. Raising the flooded leg further would adversely affect the boats stability by _______________.

A raising the KG and increasing the draft which may put you in an unsafe operating condition
B causing the vessel to yaw when underway
C increasing the righting arm on the high side
D increasing GM and causing a fast roll
AI Explanation

The correct answer is A) raising the KG and increasing the draft which may put you in an unsafe operating condition. Explanation: 1. Raising the flooded leg of a liftboat would increase the vessel's draft, which in turn would raise the center of gravity (KG) and reduce the stability of the vessel. This can put the liftboat in an unsafe operating condition. 2. The stability of a vessel is a critical factor, and raising the flooded leg would adversely affect the liftboat's stability by increasing the KG and potentially leading to an unsafe operating condition. 3. The other options are incorrect because: B) causing the vessel to yaw when underway is not the primary concern, C) increasing the righting arm on the high side would actually improve stability, and D) increasing GM and causing a fast roll is not the issue in this scenario.
