How tides help in navigation
Answers
For e.g. the speed in the first hour will be less, but will pick up in second hour & will be max in 3rd hour & will slow down a little in 4th hour & gradually decrease in 5th & 6th hour.
The reverse is true of a low tide.
In between the time of a low tide & high tide - say about half an hour - there will be practically no movement of water & I call it as “Nil tide time”.
Speed of water is very fast during tides in Gulfs as compared to bay's & open seas. In highly off shore areas one does not fell the tides.
Tides are important for coastal areas & its navigation.
Hence tide timing, its amplitude is very important for coastal navigation rather than for off shore navigation.
Depending up on height of a tide, say high tide, the speed of on coming water will depend upon it & it will change every hour of the approx 6 hours in a diurnal tide.
