A pedal boat comprises an integrally molded hollow hull having an upper surface where water passengers can be seated. The hull is provided with drain holes to conduct water away from the pedal boat. A steering assembly and paddle wheel assembly are mounted to the hull. Each paddle of the paddle wheel assembly has a terminal portion which is displaceable between a rest position, wherein the terminal portion extends at an angle to the plane of the paddle to provide a more vertical entrance angle of the paddle in the water, thereby reducing the noise factor and a, loaded position in the water, wherein the terminal portion extends in the plane of the paddle to provide a greater thrust.

Why it's free to use
- Filed April 29, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
