Question 3448 Deck General

The correct answer is C) 150 feet. The maximum recommended water depth for elevating the COASTAL DRILLER in this scenario is 150 feet. This is based on the Stability Booklet guidelines, which recommend a maximum water depth of 150 feet for vessels experiencing a single amplitude roll angle of 2 degrees and a roll period of 10 seconds. The other options are incorrect because 50 feet is too shallow, 100 feet is too shallow, and 200 feet is too deep for the given roll characteristics of the vessel.
