A system and method for tracking the position of a smart plug on a marine vehicle is provided. Generally, the system and method of the present disclosure are designed to generate indicia used to alert a user of the position of the smart plug on a marine vehicle so that the user may properly position the smart plug on the marine vehicle prior to launching said marine vehicle in a body of water. The system generally comprises a smart plug, a plug sensor, a processor operably connected to the plug sensor, and a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. In some preferred embodiments, a computing device having a user interface may be operably connected to the processor. At least one sensor of the smart plug collects data that may be used by the system to alert a user to secure the smart plug in the drain hole.

A drainage device for directing fluid away from a thru-hull fitting located on a hull of a vessel includes: a channel body mountable proximate to and extendable away from the hull of the vessel; a groove formed along at least a partial length of the thru-hull body; and a lip protruding from a bottom edge of the channel body at an end of the channel body that is distal from the hull of the vessel when the drainage device is mounted thereon.

A personal water craft includes a hull; a deck attached to, or integral with, the hull; a foot well having a foot well floor that is configured to receive a foot of a user of the personal water craft; and a drainage system configured to drain liquid from the foot well, the drainage system having a tube extending from the foot well floor to a location outside the hull.

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.

An example watercraft includes a hull that defines a cockpit. A scupper is provided that extends from the cockpit through an exterior surface of the hull. A recess defined by the hull is in communication with the scupper, and the recess defines a portion of a venturi tube. A plate that is attachable to the hull is configured to define another portion of the venturi tube such that when the plate is attached to the hull, a complete venturi tube is defined.

A sea chest, discharge tank and black water discharge tank are disclosed, each comprising a chamber preferably formed integral with a vessel hull to eliminate multiple inlets/outlets to the vessel. The discharge tanks employ a removable standpipe to effectively move a thru-hull opening from beneath the vessel water line to a position above the vessel water line. A sea chest includes a chamber for placement of a UV light to treat incoming water.

A boat safety device includes a base portion that has a boat plug retaining cavity. The boat plug retaining cavity is sized for accepting and holding a boat drain plug and is optionally threaded to match threads of the boat drain plug. A key hole goes through a wall of the base portion and is sized to accept a boat key. The key hole is interfaced with the boat plug retaining cavity such that when a key is inserted fully into the key hole, teeth of the key extend into the boat plug retaining cavity so that, after installing the boat drain plug into the boat plug retaining cavity, the key is held in the key hole until the boat drain plug is later removed from the boat plug retaining cavity. Optionally, a key guard is provided to reduce chances of bending the boat key.
