Disclosed are an extendable and retractable fairing for a container ship and a control method thereof. The extendable and retractable fairing includes a controller, a support skeleton, a wind velocity detector, a first flexible deflector, second and third flexible deflectors, and accommodation mechanisms. The third flexible deflectors are sequentially arranged between the first and second flexible deflectors; the support skeleton includes guide-track grooves; the second and third flexible deflectors each are slidably provided in a corresponding guide-track groove; the accommodation mechanisms each include an accommodation winding tube and a drive motor; the accommodation winding tube is provided at one side of a deck at the bow; the drive motor is connected to the accommodation winding tube; the wind velocity detector is provided on the first flexible deflector; and the second and third flexible deflectors each are provided in the accommodation winding tube.

A marine deck member with enhanced surface traction and the process for forming the same. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold-pressing in a mold. The cellular core has a 2-D array of cells, each of the cells having an axis substantially perpendicular to the outer surfaces, and extending in the space between the layers or skins, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be effected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be effected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.

An articulating top having a frame, a cover attached to the frame and a mounting bracket to attach the frame to a vehicle can be moved between a deployed position to provide shelter to an area below the top and a stowed position. The frame having main and secondary frame members in addition to one or more struts between a frame member and the vehicle to provide additional support to the frame such that the top can be used while the vehicle is in motion or in windy conditions. The top may also use one or more braces.

The fishing rod holder and retainer are configured to hold and retain a fishing rod in a gunwale of a boat. A cylindrical tube is coupled to a top plate and configured to extend downwardly at an angle into the gunwale of the boat to hold the butt of the fishing rod. A rod retainer includes a retainer tether having a retainer fastener at a distal end thereof and positioned for extension at the top plate adjacent the retainer opening to couple to the fishing rod. A biasing device is coupled to the retainer tether at a proximal portion thereof and configured to bias the retainer tether downwardly. The biasing device may include a spring loaded locking spool (e.g. a brake) positioned at a bottom of the cylindrical tube and configured to store a proximal portion of the retainer tether thereon.

An electric field gradient sensor is presented, having a sensor body having an outer surface; and a plurality of electrodes distributed over the outer surface, each electrode having an electrode surface facing outward from the surface. The plurality of electrodes are arranged forming a plurality of electrode pairs, each electrode pair formed by a first electrode and a second electrode located on opposite sides of the sensor body. This sensor enables three-dimensional measurements of the electric field gradient along structures located in an electrically conductive medium, such as subsea structures, for example for monitoring the cathodic protection of such structure.

Couplers for attachment to a protrusion extending outward from a portion of a boat is provided. The coupler may comprise a base having an opening adapted to receive the protrusion, the base having a locked position and an unlocked position. The base being translatable along a first direction between the unlocked position and the locked position. The coupler may further comprise a retainer positioned to hold the base in the locked position; and an accessory support extending outward from the base in a second direction angled relative to the first direction.
