Quartermaster is the highest rank attainable by a Sea Scout and is equivalent to Eagle Scout (Boy Scouts of America). The Sea Scout must attend at least three-quarters of all Ship meetings and special activities over eighteen months, demonstrate marlinspike seamanship and leadership skills, demonstrate the ability to teach Sea Scouts skills, complete a Quartermaster Leadership Service Project (community service project) and pass a council level board of review. The Quartermaster emblem is a medal consisting of the Sea Scout emblem on a ship's wheel that is suspended from a solid dark blue ribbon that is in turn suspended from a bar bearing the design of a double carrick bend knot. In 2011, 40 Sea Scouts attained the rank of Quartermaster, compared with over 51000 Eagle Scouts.
