A water intake system for a boat spray gun, including a system utilizing a port through a transom of a boat, the port positioned proximate to the bottom portion of the boat; a spray gun system; and a water intake system, comprising: a first water inlet tube having a proximal end connectable to a pump of the spray gun system and a distal end connectable to a swivel; a second water inlet tube having a proximal end and a distal end, the proximal end connectable to the swivel; a port connector connectable to the distal end of the second water inlet tube, the port connector having external threads threadingly engaging the port of the boat; and a water inlet conduit having a proximal end engageable with the port connector and a distal end positioned under the bottom portion of the boat.

An Automatic Identification System (AIS) transponder and method for transmitting vessel AIS data can include an onboard processor and database, a VHF AIS transceiver and cellular modem connected to the processor, and a navigation sub-system for providing position inputs to the processor. The processor can include written instructions for transmitting only single sentence AIS messages when the transponder is within R.sub.sAIS of a satellite but outside range R.sub.tAIS of a terrestrial AIS base station, and switching to the base station when the vessel is within R.sub.tAIS but outside of cellular modem range, R.sub.cell. While transmitting to the AIS satellite or AIS base station, portions of the vessel AIS are recorded to the database as historical data. Once within R.sub.cell, the transponder can switch to transmission via cellular modem to an AIS architecture server. Historical data can also be downloaded to complete and update the vessel AIS data profile within AIS.

A device is for holding two or more monitors at an operator chair. The device comprises an arm arrangement adapted to be shifted between different horizontal poses. The arm arrangement comprises a support structure, a first rocker arm, a second rocker arm and a third rocker arm that are rotatably attached at separate locations of the support structure via a respective first pivot, second pivot and third pivot. The support structure is adapted to be attached to or in vicinity of the operator chair. The arm arrangement further comprises a connection arrangement between the first rocker arm, the second rocker arm and the third rocker arm.

The present invention provides a wireless power-supply control assembly 100 for wirelessly controlling a boat's main power supply. The assembly 100 comprises an enclosure assembly 110, wherein a latching relay 600 and a wireless-receiver relay 300 are mounted. The wireless receiver relay 300 is controlled by commands from a wireless transmitter and causes the latching relay 600 to connect or disconnect the boat's main power. In other embodiments, an ignition-sense relay 400 is also mounted within the enclosure and disconnects power to the wireless-receiver relay 300 when the boats ignition is on. In yet another embodiment, a manual override switch 200 is provided within the enclosure for bypassing the latching relay 600 and manually connecting the boat's power.

A vehicular interface may include an electromechanical interface between a handheld electronic device and subsystems on a vehicular bus or network. In an illustrative embodiment, the interface may operate in a master mode when a handheld device, such as a tablet computer or smart-phone, is not inserted therein. In this mode, the interface may serve as a master controller and accesses and controls various subsystems on a vehicle (such as engine control subsystems, media controllers, navigation systems, sensors and transducers) as a master controller. In one embodiment, when a tablet device is inserted into the interface, the interface may automatically switch to slave mode in which it acts as an adapter or interface between the tablet device and the vehicular subsystems.
