But as their popularity has climbed, so have their speeds and their dangers.
While personal watercraft accounted for 17 percent of all boats registered in California in 1997, they were involved in 42 percent of all boating accidents. The National Transportation Safety Board recently reported that the nimble water scooters are involved in more than half of all boating accidents nationwide.
According to the California Department of Boating and Safety, accidents involving personal watercraft killed eight and injured 276 recreationists in 1996. However, the injury tally is probably much higher, as only about 10% of accidents are reported to authorities.
Over the Fourth of July weekend, two people died in personal watercraft accidents on the Colorado River.
Part of the reason for this disproportionate accident rate may involve the watercrafts' speeds which have more than doubled for some models in only five years. Moreover, many watercraft riders are not familiar with the speedy vehicles or basic boating safety rules. It is estimated that as many as 95% of personal watercraft accidents are the result of operator inexperience.
