A fishing net support system includes a boat mount configured to be mounted onto a boat hull. A linkage is attached to the boat mount. A receiver can receive a pole of a fishing net. The receiver is mounted on the linkage, such that the linkage allows pivoting between the boat mount and the receiver within a vertical plane.

A watercraft according to the present disclosure may include an outer hull that defines an interior or hull cavity, and a ballast system located within the hull cavity. The ballast system may include at least three ballast tanks longitudinally distributed along the hull cavity, and each of the tanks being configured to be independently operated enabling selective entrapment of ballast at three or more different longitudinal locations to enable an intentional shifting of the longitudinal center of gravity (LCG) of the watercraft relative to the design location of the LCG of the watercraft. The watercraft may include at least a forward, a center, and an aft ballast tank, and in some embodiments, additional tanks, in some cases in sponsons, may be included and/or one or more of the forward, center and aft tanks, may be further subdivided for additional active LCG control.

A position controller for electronically monitoring the position and speed of a dredge. The position controller consists of an electric powered line winding spool with an electric encoder to indicate line speed and position to a microprocessor. A drag control assembly with electric control is used to increase, decrease or set the drag at desired setting by microprocessor control. Touch screen microprocessor interface is the preferred method to enter settings into the system and allow display/control through multiple preexisting marine electronic devices throughout a fishing boat.

A marine vessel comprising: at least one buoyant tubular foil; and at least one baffle plate positioned about the perimeter of the at least one buoyant tubular foil so as to protrude into the flow of water passing by the perimeter of the at least one buoyant tubular foil, whereby to create a high-pressure zone fore of the at least one baffle plate and a low-pressure zone immediately aft of the at least one baffle plate, whereby to create a dense stream of supercavitated water immediately aft of the at least one baffle plate.

A stringer for having a runout with a raised area configured to reduces stress while improving drainage across the runout when utilized in a close structural component of a vehicle such as an aileron of an aircraft. In one or more configurations, the raised area of the runout of the stringer includes multiple tapered surfaces adjacent to one another oriented and configured as ramps to collectively guide water up, over and down the raised area of the stringer.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.
