Hints On seadoo personal watercraft

There is no engineering limit to the size of jet boats, though the validity of their use depends a lot on the type of application. Classic prop-drives are generally more efficient and economical at low speeds (up to about 20 knots) but as boat speed increases beyond this the extra hull resistance generated by struts, rudders, shafts etc means waterjets are more efficient in the 20-50 knot range. Also, in situations where you need very large propellers turning at slow speeds (such as tug boats) the equivalent size waterjet would be simply too big to be practical. For these reasons the vast majority of waterjet units are installed in high speed vessels and in particular situations where shallow draught, manoeuvrability and load flexibility are main concerns.

Apart from the obvious hazards of collisions and mechanical breakdowns common to all vehicles, personal watercraft feature the unique hazard of orifice injuries. Such injuries are the logical result of the unusually close proximity of PWC riders to the output end of the pump jet, as well as the fact that personal watercraft are usually not enclosed. A rider who falls (or is ejected) off the back can land directly in the path of the PWC's high-pressure jet of water. Unless a rider is appropriately dressed in garments made out of a strong, thick substance like neoprene (as is commonly found in wetsuits), the jet will easily penetrate any orifice it reaches. The consequences include permanent disability or death.For example, in 2006, the California Court of Appeal (First District) upheld a $3.7 million Napa County jury verdict against Polaris Industries arising out of one such incident (which had devastating effects on the victim's lower abdomen).
