If you are looking for high-performance, thrilling water rides, jet boats are the way to go. With these jets, you can drive at exhilarating speeds, enjoy unparalleled maneuverability and boast leap onto planes without holding back. These watercraft are uniquely different from your traditional water boat. Unlike the conventional prop and outdrive used in water boats, jet boats are powered by single or double engine configurations with an impeller that sucks water in through a grate in the hull and propels the boat.
One of the biggest factors here is safety; without a prop at the back, anyone can swim or tube near the stem without worrying too much. Another thing about jet boats is that you can practically take them any place because they have less of a draft. You can easily take your jet boat stern in and walk out into the beach without having to swim to land. Make sure the water is a couple of inches deep and has no obstructions.
With a jet boat, you can get multiple seating rooms with enough space to move around the boat thanks to the compact engines. These boats tend to be smaller and are commonly used for navigating in inland waterways like lakes and rivers or in areas near the shore.
They also make an ideal choice for family watersports like waterskiing, wakeboarding, and tubing. A jet boat is one of those crazy adventure sport boats that was originally developed by a New Zealander. These boats do not operate like regular motorboats. It has water intake systems that are similar to jet skis. The first jet boat did not have any propellers so that it would be able to navigate very shallow rivers that New Zealand is known for. With a massive jet boat like a Shotover, you can travel at an impressive 85 kph in waters as shallow as 10 centimeters.
With propellers, these boats can perform their signature degree spins. Sir William Hamilton originally developed jet boats back in the year for use in the shallow and fast flowing rivers in New Zealand. This was specifically designed to overcome the problem of propellers striking rocks. Before Hamilton, there were many attempts at making water jet propulsion but were not lasting mostly because the design of the units were inefficient and did not prove to be better than the conventional propellers.
This was the beginning of the popularity of jet boats and jet units. With further improvements down the years, water jet proved to be more advantageous than propellers for a wide variety of vessels.
Today, water jets are widely used in several high-speed vessels like patrol boats, rescue craft, offshore supply vessels, and passenger ferries. Jet-powered boats may date back to the s, but it did not enter the mainstream market until the s when the sale for jet boats and personal watercraft kicked off at an impressive rate. Both companies have signed engine supply agreements with BRP. From the earliest years of its existence in the market till date, their allure remains the same � thrilling acceleration, absence of spinning propellers at the stern and a compact power train.
A jet boat works off of thrust. Think of the thrust you feel when you hold a high power fire hose or the recoil you feel on your shoulder when you fire a rifle.
The jet pump draws water into a bowl which is then pressurized. The water then leaves the pump at a high velocity. The resultant effect on the boat is a backward moving thrust that gets the boat moving forward. Ultimately, it is the size of the impeller that determines the amount of thrust generated at a certain RPM other factors also control this but for the sake of simplicity, we will not get into it.
The size of the impeller also determines the amount of horsepower required to spin it at a certain RPM. The amount of horsepower absorbed will be directly affected by the speed at which the impeller spins.
Horsepower requirements vary with the size of the impeller. The size of the impeller decreases as the letter increases and the engine loads lesser. It also requires less horsepower to spin it to maximum RPM. But it will need lesser horsepower than impeller A to spin it at RPM. Take a close look at the Impeller curve chart I found at Berkeley. It shows you the amount of horsepower needed to spin different impeller sizes at a certain RPM.
Impeller C on the other hand only needs hp at RPM to get it spinning at the same speed. Keep in mind though, that at this rate impeller A will generate more thrust compared to impeller C since impeller A is moving more water at that given speed. The more water an impeller moves at a certain RPM, the more load an engine will get, thereby needing more horsepower to get it spinning at that speed.
However, because impeller A can move more water at the given speed, the water pressure at the pump is higher, thereby generating more thrust at the given RPM. On an average, a 16ft jet boat will weight around lbs.
An important thing to keep in mind before you set out on the water is the maximum weight of the boat and the maximum weight it can carry. Normally the capacity plate in your boat will show the max engine power. Jet boats can operate in shallow waters because it can jet water above the waterline. By ejecting water above the water line, there is no need for vents or props which can protrude right below the hull. It is also what makes the jet boats highly maneuverable because there is no drag to the hull as it skims across the surface which would otherwise disrupt changes in the direction.
Due to its high maneuverability, you can reverse most of it in full speed and bring it to a full stop within a little more than its own length. Here you will cut the engine throttle and then turn the steering sharply before opening the throttle back again.
