Abstract: A valve for use in combination with a self-bailing hole of a watercraft includes a flange, a skirt, a valve member, a retention member, and a base member. The flange has a central aperture opening into a hollow interior of the skirt. The hollow interior contains the valve member, which is movable between a sealed configuration preventing fluid flow through the valve and an unsealed configuration allowing fluid flow through the valve. One end of the skirt is secured to the flange, while the other end of the skirt has an opening larger than the central aperture of the flange. The retention member prevents the valve member from exiting the hollow interior of the skirt in the unsealed configuration, while the base member is used to secure the valve within the self-bailing hole of the watercraft.
