Boat crossing a river

Steer upstream and combine boat velocity with river flow.

Open the simulation

What to notice

Pointing straight across gives the shortest crossing time. An upstream heading can cancel drift.

Key relation

vground = vboat/water + vwater

Try this

Find a heading that makes the landing point line up with the launch point.

What you can change

• Boat speed in water: 3 to 8 m/s
• River speed: 0 to 4 m/s
• Upstream heading: 0 to 60 °
