Water scooters are water vehicles that look very much like motorcycles. Nowadays speedy, colorful water scooters are gaining in popularity. They can travel anywhere a small boat can and be typically popular with young people. Many water scooter operators are inexperienced and ignorant of navigational rules which increases the potential for accidents. The increasing popularity of the scooter has aggravated the problem providing more water vehicles to compete for the same space. In addition to the inherent operational hazards of water scooters, they’ re proving to be an environmental nonsense. Beach residents complained of the noise of the scooters. The Pacific Whale Foundation on the west coast expressed concern that the scooters are frightening away and endanger species of whale that migrates to Hawaii for breeding. Regulations such as minimum operating age, restricted operating areas and compulsory classes in water safety are essential. Without such regulations, tragedies involving water scooters are sure to multiply which makes many beaches unsafe for recreation.
