1. A voltage detection system for a marine vessel, the system comprising:
at least one electrode set configured to detect a voltage gradient measurement at a location in a body of water surrounding the marine vessel; and
a control system configured to:
receive the voltage gradient measurement from each electrode set;
compare each voltage gradient measurement to at least one threshold to determine a voltage threat level; and
generate a threat response on the marine vessel based on the voltage threat level and at least one of a battery health level and a vessel health level, wherein the battery health level is determined using at least one of a battery state of charge or a battery temperature from a battery management system and the vessel health level is determined using vessel input from at least one of a voltage sensor in a vessel electrical system, a vessel orientation sensor, a vessel motion sensor, a global positioning system, and a passenger location monitoring system.
