Question 1269Deck Safety70% to pass
Many sheath-screw davits have markings to indicate the maximum angle to which they should be cranked out. If the angle is exceeded, the davit _______________.
AI Explanation
The correct answer is A) the screw may come out of the sheath.
Sheath-screw davits have markings to indicate the maximum angle to which they should be cranked out. This is because exceeding this angle can cause the screw to come out of the sheath, which could result in the davit failing. The other options are incorrect because exceeding the maximum angle would not prevent the boat from being positioned at the embarkation station (B), would not directly cause the falls to chafe and fail (C), and would not necessarily jam the davit against the stops (D).
