A monopod for mounting to the boat seat mount of a marine vessel, such as a bass boat or speed boat, which is capable of providing power for mobile accessories via a second monopod affixed to the navigation light port of the boat. The monopod is extendable to heights up to or exceeding eight feet (8) above the deck of the boat, providing exceptional views for recording with a mounted camera while users participate in sports or other events within the boat. A release mechanism allows one portion of the monopod to telescope away from a second portion, thereby extending the monopod.

A method for increasing cargo capacity of a floating vessel with a buoyant hull for cargo, with a load line presentation device affixed to the buoyant hull without interrupting water flow along the buoyant hull the load line presentation device presenting: a baseline load line indicator plimsoll mark and a plurality of increased capacity load line indicator plimsoll marks, with an increased capacity model in memory connected to a processor in communication with the load line presentation device; the increased capacity model configured for automatically integrating a plurality of variables including: wave size, wave period, wind speed, surface current, vessel length, type of vessel, quantity of disconnected superstructures, quantity of sheer, and bow height and identifying increased capacity load line plimsoll mark for a voyage of the floating vessel, the load line presentation device displays the increased capacity load plimsoll mark improving baseline capacity of the buoyant hull from 1% to 30%.

An emergency location information service (E-LIS) for water-based network devices. The E-LIS includes a server application and server network devices that accepts emergency messages from water-based network devices. The water based network devices comprise one or more sensors or one or more actuators, a wireless connection interface including a wireless low power wide-area ultra-narrowband network interface and a wireless low earth orbit satellite network connection interface and is an automated network device capable of sensing is own environment and automatically sending out the one or more emergency messages or one or more emergency text messages without operator input to an E-LIS server network device when an emergency event occurs on a body of water. The E-LIS server network device provides a current physical geographic location for such water-based network devices and/or users of the water-based network devices in an emergency situation on the body of water such as a river, lake, sea, ocean, etc.

An electronically powered, light emitting fin used with a surfboard or paddleboard, or similar water sports board. The fin is configured to be attached to the water sports board to provide illumination under the board when using the device. The lighted fin may be particularly useful when using the water sports board at night to illuminate water beneath the board.

A method for a collision risk calculation includes: executing acquisition processing that includes acquiring travel information regarding a position and velocity of each of a first vessel and a second vessel; executing region calculation processing that includes calculating a region having a possibility of future collision between the first vessel and the second vessel from the travel information of each of the first vessel and the second vessel; and executing first risk calculation processing that includes calculating a first risk value based on a maneuvering amount used by the first vessel or the second vessel in order to avoid the region.
