Subject to drydocking. This would possibly be used by a charterer in the negotiations for a time charter in order to establish that a ship would be allowed to be dry docked by the owner but would be off hire during the ducking period.
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 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.
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 to licence being granted. This term is used in negotiations as regards the chartering of a vessel at a time when owners are not free to commit their vessel for a certain employment without having obtained the approval of competent authorities. Consequently, a charterparty issued under such condition is not effective until such licence has been definitely granted.
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.
