Camel - (1) A type of floating dock used to lift a ship over shallows on entering or leaving port.The device was first used in Amsterdam, possibly as early as the XIV century. The origin of the term is believed to be from the name of an early dock, Camel. (2) A floating fender, of a log or cluster of logs or beams, between a ship and her pier or quay when moored to the shore. In France they were called chameau, camel, the reason for which is uncertain.
Down East - Anyone who isn't familiar with the Maine Coast and its waters may ask, "why 'down'?" Two possible answers: one is that no matter where one is in New England, one always goes "up" to Boston. Another is that to sail across the Gulf of Maine, as to Nova Scotia, the magnetic course is south of east. A possible third explanation is that one sailed downwind all the way. but I would suggest not counting on this.
Make Fast - To fasten a line, especially to a cleat or to bitts. Fast is from the same word in Anglo-Saxon.
Rivet - A bolt with the headless end hammered or pounded flat after insertion. This was one technique for some fastenings in Viking ships; however, the term came into English from the Old French river, to attach.
