The watches are changed at eight bells and the same sequence of half-hourly bells repeated. The watch below is called fifteen minutes before eight bells, and it is a habit of disciplinary nautical etiquette to relieve the watch on deck promptly on the stroke of eight bells. Formr erly, the watch and watch system was universal and it is still the usual routine for deck hands, except on ships where* quartermasters are spec- ially engaged to steer the ship, in which case the deck hands are usually on whole day work, each man taking a turn on the lookout at night. The officers, however, are organised in three watches, the chief officer taking the 4 to 8 watch morning and evening, the third officer the 8 to 12 watches, and the second officer the middle and afternoon watches from midnight to 4 a.m. and noon to 4 p.m. Helm Orders.—The rudder in very small ships is turned by a helm or tiller as in the life-boats. The helm has disappeared from ocean-going ships but the name still survives and only the rudder remains the same. When it is desired to turn the ship's head to starboard, the rudder is angled to starboard by turning the steering wheel so that its upper half also turns to starboard; conversely, when the ship's head is turned to port, the rudder is angled to port by turning the, wheel sd that its upper half also turns to port, all of which sounds quite intelligible and logical. The word helm for some unexplained reason is still retained and the Board of Trade has intimated that "from 30th June, 1931, helm or steering orders to the steersman shall be given in the direct sense> e.g. when the ship is going ahead an order containing the word 'starboard' or 'right or any equivalent of 'starboard9 or 'right* shall only be used when it is intended, on ships as at present generally constructed and arranged, that the wheel, the rudder-blade and the head of the ship, shaft all move to the right." This recommendation also forms the text of Article 41 of the International Convention (1929). We, have purposely avoideS using the word helm in this book and have referred to the action of theTudder direct which, after all, is t&e apparatus that causes the ship to turn. Conning the Ship.—When the command is given "port 10°" the man at the wheel replies in a responsible manner "port 10°, sir/' and then turns*'the wheel until the indicator on the steering wheel jpjllai comes to "port 10 Y* the rudder is then at an angle of 10° with, the line of tte keel and the skip's head wiB turn in response to tike action of the In some skips the order "$K>rt 10°w would mean steer 10° to of your course.
