Drain mechanism for watercraft

Abstract

A watercraft includes a hull, an opening extending through the hull, the opening configured to receive a removable propulsion mechanism, and an insert removably insertable into the opening. The insert includes an inner cavity, an aperture configured to be at least partially submerged in a fluid when the watercraft is positioned on the fluid, the aperture being configured to provide fluid communication between the inner cavity of the insert and the fluid as the watercraft travels in a forward direction, and a surface shaped and dimensioned such that a first pressure within the inner cavity is greater than a second pressure at the aperture as the watercraft travels in the forward direction.
