(See Clause no. 98 in the Forms or Approved Documents issued by BIMCO.)
Then, the Charterer has right on an indemnity in pursuance of non-compliance of one of the warranties namely that before and at the commencement of the voyage, the ship must be seaworthy (see also paragraph c below). If the stoppage or the delay is due to an Act of God, (e.g. fog or a heavy storm) or to a fault of which he has no knowledge, then the Ship Owner owes nothing at all. A delay in putting the ship at the disposal can have the breaking of the contract as a consequence in pursuance of non-fulfilling of a "condition". (See further Cancelling Clause.)
To protect oneself against a possible delay, the delivery date in the charter party is given with a certain margin. If e.g. 15 - 21 October is mentioned then the Charterer is not obliged to accept the ship before 15 October and the charter party can, if need be, be cancelled if the ship is delivered after 21 October. This is the so-called lay/can (see paragraph Lay/can).
The ship must follow the shortest route (see also the Gencon, Clause 3, Deviation clause) and at a convenient speed or at the minimum speed which is mentioned in the charter party (exclusively under the time charter or the bareboat charter).
All those obligations, which in fact are obvious and must therefore be applied tacitly, are called the implied warranties.
Sometimes those "implied warranties" are incorporated explicitly in the contract of affreightment:
“… that the said vessel being tight staunch and in every way fitted for the voyage, shall with convenient speed proceed to….”
The ship must always be delivered back in the same state as the state in which it was received, ordinary wear and tear excepted. This is especially important under the time charter and the bareboat charter. To materialize this, at the delivery of the ship a description of the condition of the vessel (the on-charter survey report) will be established by two surveyors, one for the Ship Owner and one for the Charterer (the so-called defended survey). When the ship is delivered back to the Ship Owner an "off-charter" survey report will then be established. The possible incurred damage during the chartering period will be compensated for by a fixed sum. At the "on" and "off-charter survey", the remaining fuel on board must also be taken into account.
