System

Less prone to breakage gargoyles from floating debris than conventional screws (which can be a big plus, say, the port fleet vessels), but it also argument leads not to abandon the more complex programs to be able to oppositely directed jets 'wash' zabivshuyusya debris grate inlet. Sometimes used special mobile fingers to remove debris from the inlet. Another advantage of water jet - the surprising softness of the transmission and the almost total absence of vibration, which is important for recreational boating. Disadvantages of high cost water jet - one of the most important negative aspects. It costs about half as much as conventional rudder and steering system. For some types of boats that can result in a substantial increase to the price and will probably be rejected buyers as an unnecessary luxury. Most of the negative reaction of potential buyers focus on the steering system: control of the vessel with water-jet propelled significantly different from normal control screw ship, especially when maneuvering in confined waters. The advantage is that the water-jet propelled vessel retains full control, when the deflector is installed in the neutral position, which is especially important in narrows.

However, there are also disadvantages. The problem occurs when the driver moves from the usual single-lever control system to control the levers of water cannons. Some manufacturers try to copy the customary water cannons lever system, but rather, it is a disservice. Of course, in a sense it helps the driver to master the water-jet propulsion, but he must always remember that the water jet is not a neutral position of the lever switching speeds, as on a conventional gearbox.
