(i) a vessel engaged in laying, servicing or picking up a navigation mark, submarine cable or pipeline These vessels are often called as RAM vessels.ĭistinction: The vessels mentioned below (i – vi) must be engaged in their special operations to be entitled to the status as a vessel restricted in her ability to manoeuvre. Vessels restricted in ability to manoeuvre may or may not be underway. The term ‘vessel restricted in her ability to maneuverer’ shall include but not be limited to:īecause of the nature of her work: The status does not apply to vessels that cannot manoeuvre because of external reasons such as – they are in a narrow channel or in shallow water or because of strong currents or bad weather. (g) The term ‘vessel restricted in her ability to manoeuvre’ means a vessel which from the nature of her work is restricted in her ability to manoeuvre as required by these Rules and is therefore unable to keep out of the way of another vessel. A NUC vessel is entitled to get privileges only when she displays required lights and shapes. Rule 18 assigns the privileges and obligations & Rule 27 prescribes the lights and shapes for not-under-command vessels.
Rule 31 gives the navigation light and shape requirements for seaplanes. When on the water a seaplane is a vessel. (e) The word ‘seaplane’ includes any aircraft designed to manoeuvre on the water. Other rules: Rule-26 prescribes the lights and shapes and Rule-18 prescribes the privilege and obligations for vessels engaged in fishing Vessels fishing with trolling lines: (for example, a sport fisherman’s rod and reel with the line towed astern), which do not restrict manoeuvrability. Trawls: The term ‘trawls’ refers to large open-mouthed nets that are towed through the water by one or two specially equipped fishing vessels (trawlers). Lines: The term ‘lines’ refers to lines such as long-lines which may be miles long and to which are attached at regular intervals many leaders and hooks. Study Mariner’s Handbook for the details of pictorial fishing gears used by vessels engaged in fishing. Restrict manoeuvrability: Not all fishing gears restrict manoeuvrability. If a fishing vessel is not engaged in fishing she should display lights and shapes as per Rule-26(e). (d) The term ‘vessel engaged in fishing’ means any vessel fishing with nets, lines, trawls or other fishing apparatus which restrict manoeuvrability, but does not include a vessel fishing with trolling lines or other fishing apparatus which do not restrict manoeuvrability.Ī fishing vessel: This is a vessel used for catching fish, whales, seals, walrus or other living resources of the sea.( (SOLAS I/2)). Propelling Machinery: Operation of the engine to generate electricity or to heat water, does not make the sailing vessel a power-driven vessel, so long as the propeller (or paddle wheel) is not engaged. (c) The term ‘sailing vessel’ means any vessel under sail provided that propelling machinery, if fitted, is not being used. A day shape is required for most vessels using both sails and machinery for propulsion see Rule 25(e). Vessels propelled by machinery as well as any other means of propulsion are considered to be power-driven vessels. Propelled by machinery: Vessels propelled by oars, paddles are not included in this definition.
(b) The term ‘power-driven vessel’ means any vessel propelled by machinery. “WIG craft”: A Wig Craft is a multimodal craft which, in its main operational mode, flies by using ground effect above the water or some other surface, without constant contact with such a surface and supported in the air, mainly, by an aerodynamic lift generated on a wing (wings), hull, or their parts, which are intended to utilize the ground effect action. Inner tubes are not included, although sailboards are. “Used or capable of being used as a means of transportation”: This phrase implies the practical transportation of people or cargo. Seaplanes: A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water.
