The relationship between distance, speed and time

The relationship between distance, speed and time.

The relationship between distance, speed and time is based on the well-known formula:

Distance = Speed * Time

Distance Made Good: The distance travelled by ship between two positions in relation to the seabed. It is measured in nautical miles [Nm].

Distance Run: The distance travelled by a ship without the course alteration and with constant speed. Measure, usually, with the Log or is calculated.

Speed: The distance travelled by a ship in unit of time. It is measured in knots [Kn].

Speed range (Dead Slow, Slow, Half, Full) is determined in the ‘Progressive speed trials’ based on ‘Measured distance / mile’.

Aboard the ship are using different speeds with specific terms, such as, Economical speed, Commercial speed, Speed through the water, Speed over the bottom, Average Speed, Critical speed, Trial speed, etc.

Speed error: The Gyrocompass error which depends on the speed, the course and the latitude of the ship.

Speed made good or Speed over the bottom: Vessel speed in relation to the seabed.

Speed table: The table which contain the speeds depending on the number of revolutions of the propeller.

Trial speed: One of the important trial performed at the reception of a ship exiting the shipyard.
