At and from. This expression in a voyage policy implies that where a ship or cargo is insured “at and from” a particular port and she arrives in the port safely with the intention of proceeding on the insured voyage when the contract is concluded, the risk attaches immediately.

Abandonment. Where there is a constructive total loss (see also Marine loss), the assured may either treat the loss as a partial loss or abandon the vessel to the insurer and treat the loss as-if it were an actual total loss. 

AA AA. Always afloat, always accessible.

Always afloat. In order to prevent a vessel from being ordered to proceed to a berth where she cannot load or discharge without touching the ground or which can only be reached safely after discharging part of the cargo into lighters or which can only be reached with spring tide, the so-called "always safely afloat clause" is inserted in the charterparty. 

AWRI Additional War Risk Insurance. This is an extra amount paid to the owner of a time-chartered vessel if the ship is ordered to a port or an area in which war or hostilities are taking place and the shipowner's insurers require an additional insurance premium for the vessel to be considered to be covered against risks in that place. 

 

Additional premium.This may be payable by charterers or shippers to the cargo insurers because of the ship's age, class or flag. The charterparty can provide that this extra premium is deductible from freight or from hire. The owner should attempt to qualify a clause with such a provision by limiting the amount of deduction and also by requiring the charterer to provide proper documentation as proof of the extra insurance before the deduction.

 

Antitrust laws. When the liner conference system became formalised in the 19th century, one of the main functions was that freight rates on an agreed route would be fixed between the members to the conference. 

AH range. A range of ports between Antwerp and Hamburg in Europe. If the owner agrees with this range of ports he accepts that Antwerp and Hamburg are warranted by the Charterer as being "safe" but he may have to dispute the "safety" of any other port nominated within the range. This description of a range of ports is sometimes abbreviated to "AH.R".
