Abstract
A venting and drain arrangement for a small watercraft that is formed with a tunnel in which the propulsion unit for the watercraft is formed. The venting arrangement includes a vent pipe that extends through a venting recess formed in the hull to the engine compartment. A well is formed in the venting recess in which water can accumulate and a drain conduit extends from the well to the tunnel for discharging water to the body of water in which the watercraft is operating without necessitating holes that will be visible when the watercraft is operating.
Claims8
