[1] The intended track is a route.
Navigation and location of the ship by means of the analysis of the data provided by accelerometers and/or gyroscopes located on board, which integrate the accelerations experienced in complex electronic systems, that converted into velocities (in the 3 possible axes of displacement) and according to the observed courses, make it possible to ...

The ship may also lose momentum at wind speeds of less than 10 knots (19 km/h). [76] Under these conditions, the choice may be to wear ship—to turn the ship away from the wind and around 240° onto the next tack (60° off the wind). [78] [79] A fore-and-aft rig permits the wind to flow past the sail, as the craft head through the eye of the wind.
