CHAPTER XVII THE WATCH OFFICER The Officer of the Watch or the Watch Officer, as he is usually termed in the Merchant Service, is the deck officer who has charge of the vessel while under way at sea. On other occasions, if stopped through trouble, or because of communication with other vessels, or on occasions requiring special maneuvering, as in coming in and out of port, rescues at sea, etc., the Master assumes full charge. +The Watch Officers.+ The watch officers are usually the Chief, Second and Third Mates, on vessels of moderate tonnage. In larger craft different watches are arranged. Then the Chief Mate may stand no regular bridge watch, and the Second, Third, and Fourth Mates take this duty. In some liners it is the custom to style the watch officers, all "second" officers; namely Senior, Junior, and Extra, Second Officers. These are usually all master mariners. Junior officers of the watch are also on the bridge, attend to the conning of the course, the working of navigation and bearings, and the keeping of the bridge log, which is signed by the senior watch officer at the end of the watch.
