Ship Speed Comparison - SOG and STW

#shipspeed #SOG #STW
It is confusing for the seafarer on which ship speed to use - SOG or STW?

Let's do a ship speed comparison using both situations.

The vessel's speed is either measured with respect to water or ground.

Speed over Ground (SOG) is the speed of the vessel in one hour with respect to the land or any other fixed object such as buoys.

Speed through Water (STW) is the speed of the vessel in one hour with respect to the water or anything floating on water.
