Boat crossing a river

The velocity of a boat relative to the shore in a river crossing is the result of adding the velocity of the boat relative to the water and the veleocity of the water relative to the shore.
Adjust the boatspeed (velocity of boat relative to water) and the current (velocity of water relative to the shore) and note the effect on the overall boat speed (velocity of the boat relative to the shore).
Note also the effect of varying the heading, and how this affects whether a crossing can be made directly across. Note also the time required for the crossing under different conditions.
