Boat in Current: Rowing Speed

Boat in current as example of relative velocity. Assume the resultant speed and bearing as well as the current speed are known.

Since the velocities form a right triangle, any velocity can be found from the triangle relationships if the other two are known.
Velocity unit
If the current speed is known to be =
and the resultant boat speed is measured to be =,
then the speed of the boat is =
and it will be angled downstream at θ = °
Alternate calculations: Resultant speed and bearing Speed of current
