Question 97 Deck Safety

The correct answer is B) At least 30 days after the last entry. The GMDSS (Global Maritime Distress and Safety System) radio log must be retained on board for at least 30 days after the last entry, as per the regulations set forth by the United States Coast Guard. This requirement ensures that the log is available for review and inspection by the relevant authorities for a reasonable period. The other options are incorrect because they do not align with the Coast Guard's regulations. Specifically, retaining the log for two years (option A) or one year (option D) would exceed the 30-day requirement, while 90 days (option C) would fall short of the mandated duration.
