Safe berth. This is a description of the specific place the Charterer can send the ship for loading and/or discharging.
SSW. This is an abbreviation for "Summer Salt Water" and refers to the draught of the ship when it is loaded to its summer load line in salt water, that is, in the open sea. The summer draught is the maximum draught to which the ship can be loaded depending on the "freeboards" and "loadlines" assigned to it by the assigning authorities.
Sub-letting. It is customary to stipulate in a time or voyage charterparty that charterers have the right of sub-letting the whole or part of the vessel on the understanding, however, that they remain responsible to the shipowners for the due fulfilment of the original charterparty. In the case of a voyage charterparty, sub-letting will probably take the form of booking other cargo by charterers.
Subject to . . . Many other examples can be cited of the use of "subjects" and both owners and charterers and their middlemen, the shipbrokers, do have considerable imagination to invent and introduce new situations which are meant to influence the enforceability of a time charter or a voyage charter.
