The two Signal Flags J. D. of the Commereial Code, "You are standing into Danger," will be hoisted and kept flying until answered. In similar cases a gun is fired from English Light Ships. L APPENDIX K MANAGEMENT OF A STEAMER AT SEA, &c. GETTING UNDER WEIGH With regard to getting steamships under weigh from an open anchorage little can be said. The duty of the officer in charge of the deck is to see that all the water in the deck steam pipes leading to the winches and windlass is blown out, and that the winches are well lubricated before starting; seeing that the wheel chains are in perfect order by putting the helm hard over to port and starboard. If steam steering gear is used, it should be well looked to before starting, with the assistance of one of the engineers, also the officer should go aft and see that no boats are near the propeller. In getting under weigh from a quay or wharf where moorings are used, especial care must be taken in keeping warps and chains clear of the propeller, and an officer aft at that time is indispensable, as more mishaps occur to steamers through fouling the propeller with ropes and chains, than from any other cause. Time should always be given, if possible, to allow of the stern ropes being hove in before the engines are moved. If circumstances will admit of it, a steamer's engines should be turned over the centres both ways, ahead and astern, before casting off, to admit of the condensed water in the engines being discharged, thereby ensuring their efficacy in starting quickly. · STEAM SHIPS UNDER CANVAS As to the management of steamers under canvas no fixed rules can be laid down, owing to their masts being so differently placed. Most steamers, when under canvas with the wind on either side, carry a great amount of weather helm. This can only be regulated by reducing the amount of the after canvas. |
