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 apparatus that facilitates search and rescue, for example, in open water. The apparatus comprises a substrate with a particular geometry and a perimeter. The apparatus further comprises a cover positioned atop the substrate with the cover also having a particular geometry and perimeter, which correspond to the geometry and perimeter of the substrate. An air-tight seal seals the substrate perimeter to the cover perimeter and creates a sealed internal region. A liquid-releasable vessel holding an illuminable dye located in the sealed internal region, along with an activator that is also located in the sealed internal region. When the liquid-releasable vessel releases the illuminable dye, the illuminable dye reacts with the activator, thereby resulting in illumination of the illuminable dye. The liquid-releasable vessel comprises an opening with a release mechanism (e.g., clamp, etc.).

A watercraft propulsion system includes an electric propulsion device attachable to a hull, an indicator located above a draft line of the hull and operable to indicate to surroundings of the electric propulsion device information about the state of the electric propulsion device, and a controller. The controller has a plurality of control modes including an electric propulsion device enabled mode in which the electric propulsion device is enabled to be driven, and is configured or programmed to perform an indicator control operation in the electric propulsion device enabled mode to actuate the indicator to indicate that the electric propulsion device is in a drivable state.

A system for a marine vessel operating in a body of water includes a trimmable marine device coupled to and movable with respect to the vessel and an actuator that raises and lowers the marine device. A control module is in signal communication with the actuator. A GPS receiver determines a current and/or predicted global position of the vessel, and a processor accesses a memory storing bathymetry data and retrieves a water depth corresponding to the vessel's current and/or predicted global position. The control module compares the water depth to a depth of the marine device based on the marine device's current position. The actuator raises the marine device in response to the control module determining that the water depth is not enough to accommodate the depth of the marine device at the current position without potential collision between the marine device and the body of water's bottom.

The present disclosure discloses a system wherein coin-sized beacons can be attached to marine and other hazards such as buoys, shipwrecks, jetties and the like. The beacons can also be configured to a user's life jacket or other intimate item worn by divers or passengers. The beacon is equipped with an ability to emit sound/radio or light (Bluetooth or otherwise) waves that are detected by a user's receiving device hardware located aboard a vessel to alert the user of an approaching hazard. The signal can be configured to provide the location or distance and proximity to the vessel of the beacon and contact information of the beacon's registered owner. The beacon can continuously transmit these signals to alert oncoming vessels of the location of the beacon, or aid in the recovery of an overboard passenger or keep track of underwater divers. Further, the receiving device hardware can be adapted to a vessel's navigation system to automatically avoid marine hazards using the vessel's autopilot system.

The present invention provides an anchor alarm device which is a manually deployed weighted device attached to or near the anchor which signals to device equipment at water-level. The device detects the movement of, or physical force generated by, a dislodged anchor. When deployed, a component of the anchor alarm device rests adjacent to or as part of a seated anchor at a distance predetermined by the tolerance of the secondary rode. The secondary rode connects the device directly to the anchor, or near the anchor on the primary rode. Upon displacement of the set anchor, in excess of the secondary rode, the device alerts the user. The device utilizes sensor monitoring inside of a housing component to detect a force indicative of anchor displacement. This detection triggers a signals emission which alerts the user of the change in position. In cases wherein the anchor is not immediately retrieved, device re-arms autonomously and stops emission of the alarm signal until the next anchor displacement. The system communicates with signal devices on board or deployed near the anchoring vessel in order to alert the user.
