Boat Speed Boosts

Boats needs some kind of power or force to help them move. They can either sail, or be mechanically propelled with an engine. In the old days, a boat gained its power from hard work, either sailing or rowing. This can still be the case if you have a sail boat. But sailing boats are no longer used for work, as a general rule. These days, engines can do the job of many men, more satisfactorily and in less time.

Boat Speed

There are always drawbacks though. The problem with high speed boats is that the faster the boat goes, the more resistance is created. It is a problem of basic physics. Overcoming speed resistance has become a critical mission for boat manufacturing companies. They discovered that the shape and size of the boat both have a great impact on the resistance issue. Longer boats tend to go faster than short ones because they help eliminate the hull speed problem.

The hull speed is when a boat reaches a stage where it can't go any faster. A scientist called William Froude was the first to discover the phenomenon of hull speed. He found that the faster a boat goes, the fewer waves are created along the hull, but then a big wave around the hull and another around the stern of the boat are created. At this point, the boat reaches its hull speed because the resistance is so significant that the boat can no longer increase its speed.

There are ways of overcoming resistance to increase the speed at which your boat can travel. You could increase the power of your engine or replace it for a larger engine. Increased power tends to overcome the hull speed problem. Another method of speeding up your boat is to increase the length; the longer the boat, the faster it will go.
