Question 4244 Deck General

The correct answer is C) 30 feet. The limits of service for the COASTAL DRILLER require an air gap of 30 feet when the charted water depth is 200 feet. This is because the regulations state that for vessels operating in coastal waters, there must be a minimum air gap of 30 feet between the waterline and the lowest point of the vessel when the water depth is 200 feet or greater. The other options are incorrect because 35 feet (A) is too much, 32 feet (B) is too specific, and 25 feet (D) is too little for the given water depth of 200 feet.
