FIG. 7 shows an air cannon system loaded with a launch canister containing a prop-fouler. A pressure vessel (28) contains an inlet including a poppet valve (100) that, upon command, can be selectively placed in either a one-way flow position to permit charging of the pressure vessel or otherwise opened to trigger rapid discharge through pressure equalization with the ambient environment. The air cannon may include multiple splayed barrels or a single barrel (158). A launch canister (202), realized in the form of a tube, has a driving plate (350) that closes an end of the launch tube. The driving plate is the first point loaded into the barrel. Within the launch canister (202) a first portion of a floating prop-fouling line is stored. The prop-fouling line, such as made from Dyneema, has at its ends two drogues that, upon entry into the water, fill with water to produce drag resistance to movement of the prop-fouling line. To avoid undue stress on canopy panels of each drogue and to avoid twisting of shroud lines (312) to the canopy, a rotating shackle (310a, 310b) acts as a coupling point between the shroud lines (312) and the prop-fouling line. Only one drogue (306), its associated coupling and a selected length prop-fouling line are loaded into the launch canister, with the other drogue and its rotating shackle (310b) loaded into a cradle (166). Upon firing, gas expansion causes the rapid acceleration and ejection of the launch tube (202) and generally straight line deployment of the prop-fouling line (302).

An anchoring device may be arranged above or below a body of water and may secure or anchor watercraft to at least one vertical object and/or horizontally-positioned object. The anchoring device may provide a clamping mechanism that may secure the anchoring device to the at least one vertical object and/or horizontally-positioned object. The anchoring device may be integrated or fixed to watercraft, such as at a seat pedestal. The anchoring device also may be used without being integrated or fixed to watercraft.

The present disclosure relates to water vessels with a bow-mounted detecting system and methods for monitoring movement of an anchor at a bow of a water vessel. More particularly, a water vessel as disclosed herein can include an anchor apparatus positioned in or on a hull of the water vessel at about a bow thereof, a detecting positioned in or on the hull of the water vessel at about the bow thereof and having a forward-directed field-of-view, and a display device adapted to receive from the detecting device and display one or more captured images of the forward scene. A method as disclosed herein can comprise providing a water vessel as disclosed herein, activating the display device to display the one or more captured images, and activating the anchor apparatus so as to cause motorized deployment or retrieval of an anchor. The water vessel can particularly provide for real-time monitoring of deploying and/or retrieving an anchor using the detecting device and the display device.
