Question 1514 Deck Safety

The correct answer is B) 6 months. According to the regulations, if the Officer in Charge of Marine Inspection (OCMI) has not granted an extension, free-fall lifeboats must be lowered into the water and launched with the assigned crew at least once every 6 months. This is to ensure the proper functioning and crew familiarization with the lifeboats in case of an emergency. The other options are incorrect because 3 months is too frequent, a year is too long, and 2 years is significantly longer than the required 6-month interval.
