The DEEP DRILLER is being towed at a 20 foot draft. Vessel motions are within acceptable limits, but the waves begin to hit the horizontal braces. You should _______________.
AI Explanation
The correct answer is A) change course to reduce the wave impact.
When the waves begin to hit the horizontal braces of a vessel being towed at a 20 foot draft, it indicates that the vessel is experiencing significant wave action that could potentially cause damage. In this situation, the prudent action is to change course to reduce the wave impact on the vessel, as this will help to mitigate the risk of damage and ensure the safety of the tow.
The other options are not appropriate in this scenario. Continuing on the same course at the same draft (option B) would expose the vessel to further wave action and potential damage. Ballasting to a 60 foot draft (option C) would be an unnecessary and potentially dangerous action that could adversely affect the vessel's stability and handling characteristics. Shortening the tow wire (option D) may provide a smoother ride, but it does not address the underlying issue of the wave impact on the vessel.
