Paramount clause. (Also termed Clause Paramount.) This clause is generally found in a bill of lading but can also be found in a charterparty. The main purpose of such a clause is to incorporate the terms and conditions of the Hague or Hague-Visby Rules (or the Hamburg Rules) into the document which is (or which evidences) the contract of carriage of goods by sea. The Paramount clause can also incorporate particular legislation, such as the United States Carriage of Goods by Sea Act 1936.


CMI. Comite Maritime International. A group of international lawyers and law associations specialising in maritime law, based in Antwerp, Belgium. CMI is responsible for some documents used in chartering, e.g., for the "Charterparty Laytime Definitions". The CMI has also compiled a list of arbitrators, well-experienced in maritime arbitration and able to decide disputes arising from charters. Parties to a charter dispute can choose arbitrators from this list.


Contamination. If a cargo which is sensitive for some reason is damaged by the nature of another cargo or substance, the former is “contaminated”. This would be the situation if one grade of oil, e.g., a clean oil product on board a tanker, was loaded into a tank that was insufficiently cleaned.

Colliery. A "colliery" is a coal mine and in voyage charters for the carriage of coal the laytime agreed may depend on the working hours of the mine, if the coal cargo has to be delivered to the vessel. The word is connected to expressions that affect laytime.


Collision Liability. Around the middle of the 19th century, hull underwriters decided to extend the hull and machinery policy to embrace legal liabilities incurred by the assured in consequence of collision between the insured ship and any other ship or vessel. Liabilities resulting from contract with anything other than another ship or vessel were excluded from the cover, as were loss of life or personal injury.

Colliery working days. This is a description of type of laytime depending on the ordinary working hours of the colliery from which the coal will be delivered to the vessel. The working days are related to normal times and in normal circumstances. Colliery holidays will be "holidays" if an exception to laytime exists in the charterparty (for example, "SHEX"). If the workers in a colliery are on strike, the delay is not excepted from the laytime, unless, of course, there is an appropriate "strike clause", unless a Sunday or holiday occurs during the strike.


Centre of buoyancy (B). This is the geometric centre of the under water shape or volume of a floating object. The buoyancy force provided by the liquid in which the object floats acts vertically upwards through B.


Container sizes. The sizes of containers depend mainly on their external dimensions, so that, for example, a container can be an ISO standard “Series 1 Freight container, Rating 1AA” with external dimensions of 40 feet (length) x 8 feet (width) x 8 feet 6 inches (height). The dimensions are used in either imperial or metric units. Although much of the world has become metricated, the “box” or container is still referred to by its imperial units, for example, a FEU is a forty-foot equivalent unit (of space occupied).

Consignment clause. A charterparty may stipulate the vessel will be consigned to owners' agents or charterers' agents for inward or outward business. If charterers are entitled to appoint agents at port of loading or discharge the owner must use the services of the charterers' agent and pay for those services.


Calendar month. A vessel may be fixed on a time charter basis, either for the period occupied by a certain voyage; e.g., "for one voyage from the UK and/or Continent to Australia via port or ports in charterers' option" or for the term of ". . . calendar months, commencing from time of delivery at . . ." the port agreed upon.

Cover note. A contract of marine insurance concluded when the proposal of the assured is accepted by the insurer, whether the policy is then issued or not. For the purpose of showing when the proposal was accepted, reference may be made to the slip or cover note or other customary memorandum of the contract, although it may be unstamped.

Centre of gravity (G). The line of action of the weight (force) of a body acts vertically downwards through this point, named “G”. For a uniform block, G is at the centre. For a ship, the position of G depends on the various weights in the ship.
