Systems, assemblies, and methods for conveniently operating marine devices associated with a watercraft are provided herein. An example system includes a controller, a sensor module, and a marine device. The controller is configured to receive a user input indicating a desired action via the sensor module and transmit a signal to the marine device to cause the marine device to operate in a particular manner. The sensor module may include one or more motion sensors, and the controller may be configured to filter unintentional movement from the raw motion data sensed by the sensor module, such as due to movement of the watercraft floating on the surface of the water. Thus, the system may enable convenient and intuitive control over various marine devices associated with the watercraft.

A sonar system for a watercraft, including a shaft defining a top and a bottom end. The system includes a first attachment operatively connected to the top end of the shaft, and a second attachment operatively connected to the bottom end of the shaft including a transducer assembly. The first attachment defines a first member pivotably connected to the top end of the shaft, and a handle member rotatably attached about the first member. The second attachment defines a second member pivotably connected to the bottom end of the shaft, and a bracket member rotatably attached about the second member. The system comprises a first connector extending between the first and second members and configured to cause reciprocal movement between the first and second members. The system comprises a second connector extending between the first and second members and configured to cause reciprocal rotation between the first and second members.

Disclosed is a sonobuoy that houses at least one unmanned vehicle that may be launched from the sonobuoy. The sonobuoy may include a canister, a parachute, an unmanned vehicle, and a launch mechanism. The parachute may be disposed within an interior cavity of the canister proximate to a first end of the canister. The unmanned vehicle may be disposed within the interior cavity of the canister proximate to a second end of the canister. The launch mechanism may be disposed within the interior cavity of the canister and operatively coupled to the unmanned vehicle. The launch mechanism may be configured to launch the unmanned vehicle from the canister. The sonobuoy may further include a launch deployment mechanism that may be configured to orient the canister with respect to a surface after the sonobuoy impacts the surface in order to facilitate the launch of the unmanned vehicle.

A marine vessel control system operable to be used with a shallow water anchor and a motor. The marine vessel control system comprising a memory and a processor. The processor is configured to receive a user command to maintain a position of a marine vessel, receive sonar data, determine a water depth relative to a water bottom based on the sonar data in response to receiving the user command, and transmit a command to use the shallow water anchor and/or the motor based on the water depth.

Systems and methods for automatic navigation of a marine environment area are detailed herein. A system for navigating a marine area includes a display, a processor, and a memory including a computer program code. The computer program code, when executed, causes, on the display, presentation of a chart including at least a portion of a body of water; receives an input of at least one condition parameter associated with the desired marine environment; determines a portion of the body of water defined by the at least one condition; and displays the determined portion on the chart. The computer program code further, when executed, determines a traversal coverage corresponding to a watercraft; and determines a route to traverse the determined portion based on the traversal coverage of the watercraft such that an entirety of the determined portion is covered by the determined traversal coverage of the watercraft during the route.

Apparatuses, methods, and computer-readable medium for navigation safety and collision prevention are described herein. The apparatus may cause the collection of marine electronic data from marine data sources. Marine data sources may include a radar system, a sonar system, a position system, a tracking system, and/or a chart system. The apparatus may further determine, based upon the marine electronic data, the presence of a hazard in the projected path of the watercraft. The apparatus may determine if the hazard is within a threshold distance and, in response, may cause the watercraft to stop before reaching the hazard. In some instances, the apparatus may transmit a warning alert to the watercraft operator, and after a predetermined period of time without response by the operator, the apparatus may cause the watercraft to stop to prevent collision with the hazard.

An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

Systems and methods for conveniently providing anchoring assistance onboard a watercraft are provided herein. An example system includes a display and a processor in communication with a marine system. The processor is configured to receive marine data from the marine system and/or one or more user inputs and cause the display to show one or more anchoring locations with visual indications of the anchorage quality index based on at least the marine data and/or user inputs. The one or more anchoring locations may be shown as a heat map overlaid on a map. The system may use real-time marine data, environmental data, weather data, tide data, etc. to dynamically adjust the anchoring locations and anchorage quality index. The system may enable convenient and helpful suggestions and notifications to the user when anchoring a watercraft. Some examples provide automatic deployment of an anchoring system and monitoring of a current anchoring.

Embodiments described herein relate to generating an image of an acoustic field associated with an underwater region. A plurality of submersible sensing devices (SSDs) are disposed so as to be substantially separate from each other in an underwater region, wherein each respective SSD is configured to execute a sink/float mission. During at least a portion of the sink/float mission, within each SSD, an environmental sensor measures at least one environmental parameter, a position sensor detects position information, an acoustic detection sensor detects at least one underwater signal, and a data recording system records mission data. After the sink/float mission, a processor receives mission data from the SSDs and generates an acoustic field image. Advantageously, during the sink/float mission some SSDs can transmit an orthogonal high time-bandwidth signal to help prevent interference between SSD during acoustic detection.
