Spot market. When a shipowner or vessel operator wishes to use the vessel for tramping services, on voyage charters only, he is said to offer his ship on the spot market.
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 financing. This qualification can be used by a charterer to indicate that he is attempting to finance a transaction for which he needs a ship, for example, he wishes to purchase a quantity of bulk cargo such as sugar, and needs a ship to transport it. It can also be used by a purchaser of a ship before confirming that he can complete the purchase.
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.
