Aids to sliding and gliding for enclosed power boat racing tracks - have rollers, balls or cylinders or other mechanical elements for reducing friction.

摘要

Above the water drainage hole (11) are rollers (12), balls, cylinders or other mechanical elements for minimising the friction between the power boats and the racing tracks and either suspended and removable by being fixed or detached. The rollers, balls or cylinders are made of materials resistant to cold so that, instead of the boots, in wintertime bobsleigh runners or skates may be used. USE/ADVANTAGE - The aids to gliding and sliding on enclosed power boar racing tracks are in the form of separate parts or one integrated part.
