Abstract
Methods and systems are provided for draining water from the interior of a watercraft via a drainage valve system. In one example the drainage valve system has an outer frame housing an inner ball valve. The drainage valve system is adapted to be slidable between a first and a second position.
Claims20
A drainage valve system comprising:
- an outer frame configured to;
- slide upwards vertically to retract within a scupper of the watercraft in a first position, the first position a closed position blocking flow of water through the scupper;
- slide downwards vertically to protrude from the scupper in a second position, the second position a position open to flow of the water through the scupper;
- and
- an inner ball valve that is a buoyant sphere adapted to fit moveably within a portion of the outer frame.
2 more elements
A method for draining water from an interior of a watercraft, comprising;
- moving the watercraft through water with a drainage valve system in a first, extended position, water flowing past at least part of an extended exit port of the drainage valve system creating suction to draw water through the drainage valve system;
- and
- adjusting the drainage valve system into a second, less extended position in which the drainage valve system is fully closed between the exit port and the interior of the watercraft.
A watercraft, comprising:
- a wall with a movable valve element positioned therein, the valve having an exit port forming channels that, when extended from the wall, create suction with the watercraft moving through the water, the valve positionable in a less-extended closed position.
