Wetbike

A WetBike is a planing motorised personal water craft that is often described as cross between a motorcycle and a jet ski. The original Wetbike was introduced in 1978 by Spirit Marine, a subsidiary of Arctic Enterprises (now known as Arctic Cat).

Evolution
The original Wetbike was designed by Nelson Tyler, who became well known for his film industry camera mounts known as the "Tyler Mount". It was based on a motorcycle, replacing the wheels by skis and using a pump-jet for propulsion. It debuted in 1978, a few years after the Kawasaki Jet Ski, by Spirit Marine, a subsidiary of what is now Arctic Cat.

At rest, it resembles a sit-down jet ski. Gaining speed, it would eventually lift up on the skis, and plane. The directional control was by turning the handlebars, not rotating the hydrojet like for the jet ski. Originally, the Wetbike was powered by a Suzuki two-stroke engine. During the latter years of Wetbikes (late 1980s) there were considerable advances such as 60 hp Suzuki 800 cc engines, and the Metton hulls, which were much lighter than previous models.

Eventually the Wetbike gave way to the new personal water craft (PWC) such as the Yamaha WaveRunner, mainly because they are much easier to ride. They were last produced in 1992. The design was later sold to Kawasaki.

Appearances in media
The first appearance of a Wetbike was in the 1977 James Bond film The Spy Who Loved Me. In a scene near the film's end, Bond is seen riding the Spirit Marine prototype to villain Karl Stromberg's submergible fortress. Bond refers to the Wetbike as a Q gadget.

Wetbikes appears in the 1982 CHiPs episode "Overload". After a short recreational excursion, the lead motorcycle police officers use them to chase down thieves trying to escape in a speedboat. A sign in the background indicates that the bikes could be rented for $10 per hour, or $75 for a full day.
