What is meaning of Track reach of ship?

Track Reach is defined as a distance along the vessel’s track that the vessel covers from the  moment that the “full astern” command is given until ahead speed changes sign.


 Track Reach Criteria

The stopping ability of the vessel is judged using a full astern crash stop maneuver. Based on IMO requirements the track reach should generally not exceed 15 ship lengths (measured along the path).

However, in the case of low-powered large displacement vessels, this value may be modified, but in no case should exceed 20 ship lengths, subject to special consideration and approval by the Bureau.

Determination of whether a vessel falls into the category of “low powered large displacement vessels” also will be done by the Bureau.
