Perhaps more critical than this is the trial condition in which you have to move a ship where the guarantee terms come into play. When the ship is going out for trial, normally the conventional method is move the ship near the shore. What is normally known as a measure mile test? Have you aware of this? That is, after the ship is built, the builder has to satisfy the owner that the speed for which the contract was signed has been achieved. So, the ship has to be taken out and trial.
