A device that can provide sustained release of a detectable marker into a surrounding body of water as well as methods of forming the device and methods of using the device. The devices and methods can be utilized to locate people or vessels, e.g., by search and rescue personnel, following the disabling of air or water vessels of any type or size on/in a body of water. The devices include multiple, separated layers that each include a detectable marker, e.g., a fluorescent dye. The dye-containing layers are separated from one another and sequentially released over a predetermined controlled period of time and as such the device can continue to release a detectable marker over an extended period of time into surrounding water.

Various implementations described herein are directed to providing lighting in an underwater transducer mounted to a boat. The transducer assembly includes a housing. The housing includes a transducer. The housing includes one or more lighting devices. The housing also includes an element integrated with an outer edge of the housing in a waterproof configuration. The element allows light from the one or more lighting devices to emanate outward from the outer edge of the housing.

The present invention relates to a ship-collision prevention system and method for preventing a collision between a ship at sea and another ship, and according to the present invention, provided is a ship-collision avoidance guiding system using a time series graphic display, and in order to solve problems of a conventional electronic chart display and information system (ECDIS) and navigation systems using the same, which have a disadvantage of a complex and unintuitive screen display because of a simple enumeration of various pieces of information on a screen, the guiding system displays, in a time series graph, changes in relative distance according to time with respect to respective ships and obstacles on the basis of information provided from the ECDIS and a radar system, wherein, in a case of ships, whether the respective ships are on portside or starboard is displayed on the basis of radar information, and if a distance to a specific ship has a predetermined threshold value or less, the guiding system is configured to notify, through an alarm and the like, avoidance to a ship having the obligation to keep out of the way, thereby enabling the positions of an obstacle and a ship nearby at sea, crossing event time, and whether the ship is to be avoided to be easily identified at a glance, and effectively preventing a collision between ships at sea, and simultaneously, enabling a simulation for a crossing event and avoidance by inputting a random value.

A new invention for use in an emergency search and rescue situation. A simple, back-to-basic visual locator target easy to be seen from the air during the day or night to quickly locate and rescue the user in an emergency or distressed situation. The (1) circular single-layer of bright, neon material used for this target may preferably have a diameter of 25 and be a strong, lightweight nylon parachute material which can also be used as a temporary shelter if needed until rescued. The vivid neon red-orange color will make it easy to be seen during the day and the neon lime-yellow color in the center and around the edge will glow-in-the-dark and inflate for water use making it easy to be seen at night for a quicker rescue. It can be used on land by laying it on the ground and securing it by using the (3) eight anchor hook connectors; (4) eight anchor hooks; & (5) 2 lb. rubber mallet for anchoring. It can also be used to float in the water with the inflatable, luminescent circumference, center and cross-sections of the target which includes an inflatable chamber therein. The (8) manual back-up air valve system requires the user to blow their breath into the air valve and the automatic inflation requires pulling a cord that causes a mechanism to puncture a (7) (CO2) compressed air cylinder, which then expels to rapidly inflate the bladder. The (6) quick-release pull-cord has a bright red reflective handle, and when pulled, inflates the joined (2) 12 wide tubular circumference, the 4 circular center and four 48.5 cross-sections. The method activates a single pin which is located on the top of the cylinder of compressed air as a deployment handle, which when pulled, releases the bottom of the cylinder and allows the inflatable areas to automatically inflate. The (9) swivel-hook and (10) rope can be used to connect the unit to the boat or user. The lightweight carry bag (11) is easy to carry and store the unit in a variety of places.

Accordingly, there remains a need for an emergency visual search and quick-rescue aid unit that is also inflatable for rescue operations where it is easy to use and inflate if needed. It will include a compact, lightweight carrying case for easy transport, is readily accessible to anyone in time of need, and can be easily stored in a variety of places.

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.

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.
