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.
Subject approval of relevant authority. This affects the enforceability of a charter if the ship's certification and cargo handling capabilities are required to meet with official approval. For example, if a vessel is not provided with a valid "document of authorisation" it may not be allowed to load grain and the charter may depend on permission being granted to load.
Subject to strike and lockout clause. In a similar manner to "subject to dry-docking clause", this qualification indicates that the parties are in agreement to all the terms provided one party accepts the wording of a clause setting out the rights and responsibilities of the parties should the event mentioned take place.
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.
Subject shippers' approval. Like the previous restriction, this is also a "condition precedent" which can cause the fixture to fail to be binding if the shippers do not accept the ship to load the cargo. Again, also like the previous restriction, this can require a third party's approval before a charter between the owner and the charterer becomes binding.
