One way is to ensure that the hull is as smooth as possible to minimise drag through water- use an antifoul coating to minimise organism growth in the surface which could cause drag. Another method is to include an arrangement of ridges in the hull, these can be designed to lift the boat out of the water more at speed, reducing the contact and drag with the water.
There's friction between any 2 contacting surfaces.
Okay 2 ways for the friction to increase is speed and non lubricant

Going faster and run fast
If you minimize the boat down 3 times, it will make it across and a new one will appear. Every time you minimize, it moves to boat around 1 and a half inches. If you do it 2 times, the next boat won't be far enough, and the boolies will fall into the water.
A lubricant such as oil and ball bearings are just (2) methods of reducing friction.

you can get old piece of wood
1. By friction. 2. by magnetism
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.
1)increasing the roughness of the surface 2)increasing the mass of the object
