21 km/h in the rivers frame of reference.
Add the rivers velocity to the boats velocity
If the motorboat was hindered in its ability to maneuver, such as a tug pulling a boat or pushing a barge, or if the motorboat was adrift or signaling distress. Understanding the rules of underway and give-way are important parts of maritime safety.
sail boat has the right of way and same applies to all other boats larger than yours

That would be a hovercraft. However, hovercraft are not really boats and can travel on both land and water.

when 2 boats r traveling close to each other,the velocity of the water inbetween the boats increases.As a result the pressure inside it decreases (according to bournalies theorm)..the pressure shud remain constant per unit volume..hence in order to equalize its pressure in the fluid, the two boats cosequently gets attracted..even it can demage them both..hope it works!
There are sail boats, ugly boats, pretty boats, speed boats, fun boats, unfun boats, amazingness boats! i luv boats! i own a boat!!there are sail boats row boats speed boats paddle boats
