oars
the motor
depends on the boat 8.7
drag boats have seen speeds of 250 mph +
5 knots
eeeeeeeeeeewwwwwwwwwwwwww!!!!!!!!!!!!!!!
the transmission makes it go fast
the highest recorded speed in a boat is 15 mph.
The fastest rc boats in my opinion are the ones made by Fine Designs. These are extremely fast. I've witnessed a custom Fine Design go over 140mph. Is that fast enough for you?
Boats have a pointy bow because of aerodynamics. This let's the boat float while still being able to go fast.
It will vary on the engine of the boat. Including the cargo. How heavy the cargo is.
because planes are fast and they can go to place that boats, cars, ect. can not. and for quicker transportation
