Anchoring Large Vessels

London: The Nautical Institute, 2000. 23 p. — ISBN: 1-870077-56-3.This skill is not taught in college and it is not taught at sea. People arrive on the bridge on their first command, having learned the habits of the people whith whom they happen to have served. Due to lack of maintenance of anchor equipment and the increasing size of ships over the last forty years, more and more masters walk the anchor back all the way. This is not generally a good idea, for a number of reasons, as will be shown, though on occasions it may be unavoidable.ContentsSummary
