Question 4510 Deck General

The correct answer is B) 100 feet. The American Petroleum Institute (API) recommends checking the length over 5 links of anchor chain every 100 feet. This is because anchor chain can wear and degrade over time, especially in harsh marine environments. Regularly inspecting the chain at 100-foot intervals helps ensure the integrity and safety of the anchoring system. The other options are incorrect because they do not align with the API recommendation. Checking the chain every 10 feet (A) or 250 feet (C) would be too frequent or too infrequent, respectively. Checking every 500 feet (D) would be too long of an interval to effectively monitor the condition of the anchor chain.
