A segmented-foil divertor for marine towed application, such as marine seismic exploration, having a plurality of longitudinally stackable foil segments with an internal conduit extending along the span of each segment to receive a cable passing therethrough.

A subsurface battery system includes a ballast mass at the seafloor, a deep-sea electronics module, having an interface to seafloor payloads, and a subsurface buoyant pressure vessel having a battery. The ballast mass is attached to the deep-sea electronics module. The deep-sea electronics module is connected to the battery. The subsurface buoyant pressure vessel is submerged to a water depth of approximately 50 meters to 500 meters. The system is used for powering the seafloor payloads.

A vessel mounted multi-directional signal assembly includes a multi-directional signal display assembly comprising a plurality of signal display panels. Each of the plurality of signal display panels comprising at least one display surface, and a plurality of signal indicia are affixed onto different ones of each of the plurality of display surfaces. A signal support assembly is provided such that the multi-directional signal display assembly is disposable into a deployed orientation about the signal support member. A vessel mount assembly is operatively interconnected to the signal support assembly and comprises a mount member to facilitate deployment of the multi-directional signal display assembly on the vessel.

A buoy comprising: an annular upper portion disposed on a lower portion; a drain hole disposed in the upper portion proximate to the lower portion; a handhold disposed in the upper portion distal to the lower portion; an attachment member disposed in the lower portion and protruding from a bottom of the lower portion, wherein the bottom is opposite the upper portion; and wherein at least one of the upper portion and the lower portion comprises a closed cell foam.

A marker buoy constructed of a main shaft extending vertically when in use and including a marker flag, a floating body, and a spool mounted to the main shaft.

A rifle flotation device for providing buoyancy to a rifle with a rifle rail system is disclosed. The device includes a buoyant body with a first and second keyed rifle rail slots constructed to allow the rifle rail system to be inserted therein. The buoyant body may further include a first buoyant body portion that includes the first keyed rifle rail slot and a second buoyant body portion that includes the second keyed rifle rail slot. The first buoyant body portion is detachable from the second buoyant body portion and the body may further include an interlocking tongue-in-groove system that attaches the first buoyant body portion to the second buoyant body portion.

The present invention belongs to the nautical field, specifically to the area of buoys. The invention relates to a buoy for checking the condition of a person or an object tied to the said buoy. The essence of the buoy according to the invention is in that it comprises a casing, which floats on the water surface, and a capsule with a camera and lights, which can be separated from the casing with a UTP cable and can be lowered down to an anchor, an object or a person. The wire rope, which is connected to the lower part of the capsule can be connected to any anchor, a fixed object on the sea bed or a person. The camera captures images and/or video and sends data via the UTP cable to the processor, and the processors sends data via wireless network (WiFi or similar) to the mobile application installed on the user device, which is preferably a smart phone, a tablet, computer or a similar device. The user can visually check the condition of the anchor and simultaneously monitor the anchor position via one or more satellite systems for global navigation, and the position is displayed graphically and numerically on the application on a mobile telephone, a tablet or a computer.
