| 20090050042 | Method of and apparatus for detecting and controlling bilge water in a sea vessel - An improved bilge water level monitor, alert and control system for boats and other vessels. The system provides a method of detecting excessive leakage of water into the bilge and in response to the excessive water in the bilge, triggering an alarm to notify the operator and others and energizes bilge pumps to remove the excessive water. The system is designed with many redundancies in the sub elements and subsystems for safety. The system provides a means for reducing the likelihood of exhausting battery power in the event of a significant seawater leakage problem. The electrical power rating of the monitoring circuitry components is relatively low, thereby reducing the size and weight of those components relative to prior bilge pump monitoring and alert systems. There is no electrical wiring exposed to bilge water during system operation thereby reducing damage to the wiring components. The water level detection and control circuitry operates with sufficiently low amperage to substantially eliminate the hazard of spark-induced combustion. | 02-26-2009 |
| 20090107383 | APPARATUS FOR PLUGGING A SEACOCK EXTERNALLY - This invention is directed to a thru-hull fitting or specifically a seacock which is below the normal waterline of a marine vessel and this invention provides an exterior plug to stop leakage and/or allow for maintenance of the interior hull valve, piping, and/or associated tubing without necessitating the need to haul out the vessel. The seacock plug includes a rubber bellows assembly; o-ring flange assembly, sealing wedge, and compression lead screw with T-handle that forms a watertight seal around the irregular interior shape hull fitting. | 04-30-2009 |
| 20110308441 | Personal watercraft apparatuses, systems, and methods - A system for electrically expelling water from a personal watercraft includes a waterproof container. The waterproof container defines a volume, which contains a portable source of electrical power, the portable source of electrical power is within the waterproof container. A fluid movement device is electrically connected with the portable source of electrical power and the fluid movement device is outside the waterproof container. A switch is electrically connected to the portable source of electrical power, the switch has an on position and an off position. A first mounting bracket has a first end and a second end, the first end has a first mounting position. The fluid movement device is attached at the first mounting position and the second end is held under a seat of the personal watercraft. When the switch is in the on position, the fluid movement device will pump water and when the fluid movement device is in the off position, the pump will not pump water. | 12-22-2011 |
| 20120272886 | SELF LOAD SENSING CIRCUIT BOARD CONTROLLER DIAPHRAGM PUMP - A self-priming diaphragm pump is connected to a circuit board which activates the self-priming diaphragm pump at predetermined intervals, e.g., for 1-3 seconds. When the self-priming diaphragm pump is activated, the circuit board senses the amperage draw from the pump's motor and either continues to run the pump or stops the pump depending on the different amperage levels read. If there is water present in the bilge, the motor is working harder, requiring more amperage and circuit board keeps the pump running. If there is no water present for the pump to draw, the amperage load is very low and the circuit board shuts the pump off, retesting it in the predetermined interval. | 11-01-2012 |
| 20130145975 | Battery Operated Small Craft Bilge Pump - A small lightweight battery operated remote switched bilge pump is provided weighing less than one pound for installing in a small watercraft, including a kayak, canoe, sailboat, row boat, dingy, featuring a bilge pump comprising a low voltage inline pump, a housing having a compartment with an integrated strainer base and configured to receive the low voltage inline pump, and having a watertight compartment to receive lightweight batteries to power the bilge pump for about 1.5 hours, and a switch assembly to selectively operate on/off functionality of the bilge pump remotely; and a Velcro® arrangement to couple the bilge pump to a surface of the small watercraft to allow easy installation of the bilge pump in about 15 seconds to perform bilge pump functionality without drilling or making holes in the small watercraft, and to allow easy removal of the bilge pump for cleaning and battery replacement. | 06-13-2013 |
| 20140048004 | METHOD OF AND SYSTEM FOR EVACUATING FLUID IN A SEA VESSEL - A system and method that controls the evacuation of fluid from a sea vessel and configured to prevent turning off the bilge pump during periods of water sloshing. The invention provides a control unit that is adaptable to any size vessel or bilge pump based on a learned experience gained by sensory information. | 02-20-2014 |
| 20140196651 | Valve Assembly for a Bilge Pump System - A valve assembly for a bilge pump system having first and second bilge pumps each connected to a single hull outlet includes a valve body having a first inlet port for connection to the first bilge pump, a second inlet port for connection to the second bilge pump, and an outlet port for connection to the hull outlet. A first one-way valve operates at the first inlet port for allowing flow into the first inlet port to the outlet port and preventing flow out of the first inlet port from the second inlet port and/or the outlet port. A second one-way valve operates at the second inlet port for allowing flow into the second inlet port to the outlet port and preventing flow out of the second inlet port from the first inlet port and/or the outlet port. The valve assembly enables the second bilge pump to be connected to the single hull outlet and eliminates the need to cut an additional outlet opening in the hull. | 07-17-2014 |
| 20140230710 | SYSTEM AND METHOD FOR DISCHARGING A WASTE FLUID - The embodiments herein relate to a system for discharging a waste fluid from a floating unit ( | 08-21-2014 |
| 20150040813 | Overflow device for a vessel - A passive overflow device for draining away head water standing above settled sand in a loading space of a hopper, wherein the passive overflow device extends along a longitudinal axis and includes: an inlet for taking in the head water; an outlet section having an outlet for opening out in the outboard water and which outlet is level adjustable into an active position wherein in use, the head water is delivered proximate the sea bottom; a conduit which extends along the longitudinal axis of the passive overflow device and which conduit fluidly couples the inlet and the outlet; and a supporting structure for coupling the overflow device with the loading space of a hopper, wherein, the outlet section includes an flexible portion proximate the outlet for preventing mechanical overload to the supporting structure when the outlet, in use, in its active position accidently abuts the sea bottom. | 02-12-2015 |

| 20130269581 | BAILER - A bailer for a watercraft which is open on two sides, i.e., the rear and one adjoining side, enabling more efficient drainage of water from a watercraft. An adjustable bailer is provided which may include a handle with indexed positions which allows the user to easily adjust how far the bailer is open to suit conditions. The handle can be operated by either the hand or foot. The indexing function enables a user to judge how far the bailer is open or closed. | 10-17-2013 |
