Question 377 Deck Safety

The correct answer is B) Horizontal motion with a white flag. The United States Coast Guard Navigation Rules and Regulations Handbook states that a shore rescue unit should use the signal of "Horizontal motion with a white flag" to indicate "Landing here highly dangerous" to vessels in distress. This signal is part of the International Code of Signals used to communicate critical information between ships and shore-based units during search and rescue operations. The other answer choices are incorrect because they do not match the specific signal prescribed in the regulations for indicating a dangerous landing area to a vessel in need of rescue.
