A towed array ballasting unit includes a canister, an internal bladder, an external bladder, a motor valve, fluid, a shroud, and printed circuit boards. The canister includes a head endcap and an aft endcap with the internal bladder located within and attached to an internal end of a fluid channel. An external bladder is located outside the canister and attached to an external end of the fluid channel. The motor valve is attached to the aft endcap of the canister and the internal end of fluid channel. The fluid moves between the internal bladder and external bladder via the fluid channel. The shroud forms a shell around the canister, external bladder, and a connector that connects the towed array ballasting system to an array tail. The printed circuit boards execute instructions provided by a computer.

A dynamic active control system (DACS) configured for: (1) total vessel pitch axis control by fast symmetric deployment of water engagement devices (WEDs) or controllers, coupled with engine trim adjustments; (2) total roll and heading control by differentially deploying WEDs to counter rolling motions while simultaneously adjusting engine steering position to counter the steering moment associated with WED delta position; and (3) adjustment of the engine steering angle to counter yaw moments produced by gyroscopic stabilization systems.

A system and method for tracking the position of a smart plug on a marine vehicle is provided. Generally, the system and method of the present disclosure are designed to generate indicia used to alert a user of the position of the smart plug on a marine vehicle so that the user may properly position the smart plug on the marine vehicle prior to launching said marine vehicle in a body of water. The system generally comprises a smart plug, a plug sensor, a processor operably connected to the plug sensor, and a non-transitory computer-readable medium coupled to the processor and having instructions stored thereon. In some preferred embodiments, a computing device having a user interface may be operably connected to the processor. At least one sensor of the smart plug collects data that may be used by the system to alert a user to secure the smart plug in the drain hole.

A water area object detection system includes a first imager to image an object around a hull, a second imager provided on the hull such that an imaging direction of the second imager is the same or substantially the same as an imaging direction of the first imager and operable to image the object around the hull, and a controller configured or programmed to perform a control to create a water area map around the hull based on images captured by the first imager and the second imager. The second imager is spaced apart in an upward-downward direction of the hull from the first imager, and the first imager is spaced apart in the imaging direction from the second imager so as not to overlap the second imager in the upward-downward direction perpendicular to the imaging direction.

A water area object detection system includes an imager to capture an image around a hull, and a controller configured or programmed to perform a control to detect a feature point corresponding to an object in the image together with a distance to the feature point based on the image captured by the imager to create a water area map in which an object presence range including a likelihood that the object is present is set around the feature point. The controller is configured or programmed to reduce the object presence range as the distance from the imager to the feature point decreases, and set a size of the object presence range to a lower limit when the distance from the imager to the feature point is equal to or less than a predetermined distance.
