Dock water allowance (DWA). When a vessel moves from salt water to water of lower density it will increase its draught and vice versa.
Deviation and bills of lading. Under a contract of carriage if a party intentionally moves away from the agreed method of performance of the contract such departure is known as a "deviation". Hence, in the United States, a serious breach of contract is called a "deviation". However, this word is generally used for a ‘departure from’ and ‘return to’ a customary, geographical route during a sea passage. This departure is considered to be "geographical deviation" and the use of "deviation" in the context of a general breach of contract may be confusing. In the U.S., a serious breach of the contract may also be termed "quasi-deviation". In Continental countries, a, serious breach is called a "rupture of the contract".
Deviation clause. The word "deviation" can have a geographical meaning, where the vessel departs from its usual or customary route and then returns to it, or a purely legal, contractual meaning, where the contract is performed in a manner that is not originally contemplated, and this would be a departure from the manner agreed in the contract or implied by law. As an example of the latter form of "deviation", cargo may be carried on deck when deck carriage is neither authorised nor acceptable, depending on the nature of the goods. For example, in The Chanda, the vessel carried delicate, sophisticated and expensive computer equipment on top of Number 1 hatch, close to tile forward part of the Vessel. Heavy weather damaged the cargo severely. This was a deviation from the contract of carriage and because of this the carrier was permitted to rely on the terms of the contract to limit his liability for loss or damage. The owner had breached the contract of carriage.
Damages for detention. "Damages" is the legal word for compensation or indemnity for loss suffered for a breach of contract. (It is also payable for breach of "tort", another branch of law, but this does not concern us here.) The amount of damages is, generally, the amount of loss actually suffered by one party by the failure of the other party to perform the contract. The contract is the charter. Damages can be "liquidated", that is, agreed by the parties as compensation.
Despatch money. Despatch money (or simply "Despatch") is the compensation paid to charterers provided the charterparty contains a stipulation to this effect if the loading or discharging operations are completed within the laytime allowed by the charterparty, that is, before the agreed laytime has expired. In other words, despatch money is the opposite of demurrage. The reason for the compensation is to reimburse charterers, shippers or consignees for any expenses they may have incurred in order to save time to the vessel. Despatch is not payable if the charterparty does not contain a clause providing for its payment.
