A power system of a vessel includes a first AC bus; a second AC bus; a bus tie that electrically disconnects the first AC bus and the second AC bus when in an open position; a first power source and a first set of one or more non-propulsion components of the vessel that are electrically connected to the first AC bus; a second power source and a second set of one or more non-propulsion components of the vessel that are electrically connected to the second AC bus; a DC bus; a first transformer that galvanically isolates the DC bus from the first AC bus; a second transformer that galvanically isolates the DC bus from the second AC bus; a first AC/DC inverter coupled between the first AC bus and the DC bus; and a second AC/DC inverter coupled between the second AC bus and the DC bus.

A system and method for remotely monitoring marine vessel data using NMEA 0183 and NMEA 2000 data standards. The system comprises a computing device with communication interfaces for connecting to a vessel's NMEA 0183 and NMEA 2000 data systems and internet connection, a data cache for storing vessel data, and a software application. The software application receives vessel data via the interfaces, transmits it in real-time to a remote server using the internet connection, stores it in the data cache when the internet is unavailable, and transmits stored data upon reconnection. The software can also receive user-specified configuration settings from the remote server to control data transmission. The method enables secure, real-time remote access to vessel data, facilitating vessel tracking and performance monitoring without relying on traditional methods.

Remotely monitoring and combining marine vessel position, Automatic Information System (AIS), and marine electronic device output data using NMEA 0183 and NMEA 2000 data standards via terrestrial and satellite broadband (non-VHF) connections. A computing device with communication interfaces for connecting to a vessel's NMEA 0183 and NMEA 2000 data systems and internet connection, a data cache for storing vessel data, and a software application including Secure Hash Algorithm 2 (SHA-2) encryption. The software application receives vessel data via the interfaces, transmits it in real-time, applying SHA-2 encryption, to a remote server using the internet connection, stores it in the data cache when the internet is unavailable, and transmits stored data upon reconnection. The method enables secure, real-time remote access to vessel data, including AIS data from nearby ships, facilitating vessel tracking and performance monitoring without relying on traditional methods, especially terrestrial and satellite VHF-band AIS receivers.
