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.

Each anchor 20/202/204/206/208 is configured to receive two or more mooring lines 200/212, wherein each of the mooring lines 200/212 are from a different one of the plurality of floating wind turbine platforms 10.

A floating cryogenic storage structure includes a hull with a center line extending in a length direction and two longitudinal side walls, the structure including at least three spherical storage tanks, two tanks being situated with their midpoints on spaced apart longitudinal positions along a first line extending in the length direction at a first side of the center line and a third tank being situated with its midpoint on a longitudinal position on a second line extending in the length direction at a second side of the center line, and a transverse distance between the first and second lines not larger than a diameter of the tanks and the longitudinal position of the midpoint of the third tank situated between the longitudinal positions of the midpoints of the first and second tanks.

A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around its yaw axis which affects the quiet regions in the wake. Yaw rotation may be measured via one or more sensors. Yaw measurement may be used to control the hull and quiet regions. A trim tab is supported by the hull at the stern of the hull. The trim tab comprises a primary subtab and a secondary subtab. One or more actuators may be optionally included to reposition the trim tab more into, or more out of, the water to create a surf left and/or surf right configuration. Other systems and methods are also provided.

An assembly for a watercraft according to an example of the present disclosure includes, among other things, a flotation device defining an elongated slot extending between opposed ends of the flotation device, and an elongated mount that has first and second flanges extending outwardly from a bracket body. The first flange is configured to be mechanically attached to a frame, and the second flange is slideably received in the elongated slot to secure the flotation device. A method of assembly for a watercraft is also disclosed.

A process and associated system for creating color effects using extrudable material, such as plastic and metal for example, are presented. Flows of first and second viscous materials of respective colors are provided and then combined in a predetermined pattern to form a stream of combined viscous material. A dynamic mixer is the then used to apply a predetermined dividing, overturning and combining motion to the stream of combined viscous material to partially mix the first viscous material and the second viscous material, such that upon exiting the dynamic mixer, the first material of the first color and the second material of the second color form a color pattern in the stream of combined viscous material. The dynamic mixer has elements configured for acquiring a specific radial orientation in a range of radial orientations that may be varied during the application of the dividing, overturning and combining motion to the stream of combined viscous material to cause variations in the color pattern in the stream of combined viscous material. Sheets of extruded material may be created using such process and system and used in the manufacturing of many different products including, but not limited to, kayaks, stand-up paddle boards, garden furniture and many others. In some embodiments, the sheets may be characterized by color bands extending diagonally with reference to a longitudinal extent of the sheet.
