Techniques are disclosed to enable a system for controlling the propulsion and steering of a boat by a boat operator. The boat has at least one propulsion and steering motor assembly connected to the boat with a propeller, and a propulsion motor. It also has left and right pivoting pedals to provide a signal that controls the angle of the propeller so that if the left pedal is pivoted in a first pivot direction by a first percentage and the right pedal is pivoted in a second pivot direction by a second percentage, the boat executes a turn, moves forward, or moves in reverse.

An adjustable seat has a seat base having a front end and a rear end, a front leg assembly having a top end engaged with the rear end of the seat base and a bottom end opposite the top end for engaging a supporting surface, and a back leg assembly having a top end engaged with the front end of the seat base and a bottom end opposite the top end for engaging the supporting surface. The back leg assembly is pivotally connected to the front leg assembly between the top end and the bottom end of the front leg assembly and the back leg assembly. The adjustable seat has an adjustment assembly for selectively locking the front leg assembly relative to the back leg assembly at one of a plurality of lockable positions between a first position and a second position.

A kayak with additional drive formed with a hull whose part is a bottom and a deck in which is formed a crew chamber equipped with a seat and which is equipped not only with an electric engine, which is coupled with a screw-propeller, but also with a battery, which is electrically conductive way connected with the electric engine, where the electric engine is placed on a supporting frame in the back end part of the kayak and is, by help of at least a drive element, which is by its end part waterproof way freely pivoted in the stern of the kayak in axial direction, coupled with the screw-propeller, whereas the battery is placed in a battery box which is placed in the front end part of the kayak.

A support for a vessel such as a kayak or canoe comprises a support structure such as a kayak rack supported by the ground, the support structure comprising a beam for supporting the vessel, the beam generally parallel to the ground. A sliding structure is on the beam. The sliding structure comprises a bracket having an upwardly facing surface; and roller bearings on the upwardly facing surface of the bracket for ease in slidingly placing and removing the vessel from the support structure. A fastener fastens the sliding structure to the beam.

System and methods are provided that relate to a drive arrangement for propelling a boat, in particular a kayak. In some embodiments, the drive arrangement can include an electric drive motor with a shaft and a receiving device for receiving the shaft. An arresting element can be provided for determining a first desired distance along the shaft between the receiving device and the drive motor.

A foam product includes a foam core, a soft skin covering the foam core, and a base structure on which the foam core is disposed. The foam core of expanded beads has an outer surface on which some outermost beads of the expanded beads are exposed and bulging outward with different heights to form a bubbly texture. The foam skin has an inner surface attached to the outer surface of the foam core, and has at its inner surface a plurality of concave cavities each matedly surrounding a respective one of the bulging, outermost beads on the outer surface of the foam core.

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.
