The swivel lock quick release device is adapted to selectively attach a user to a sports equipment. The sports equipment may be watersports equipment, such as a surfboard, a kite surfing apparatus, a stand-up paddle board, sailing equipment, a wake board, etc., or land sports equipment, such as fishing, camping, climbing, animal collars or leashes, tactical rifle apparatus, and hunting equipment. The swivel lock quick release device can have a pull release and a protrusion, the pull release and the protrusion being adapted to be selectively engaged in a locked position is provided. A slide handle, a portion of the pull release, is adapted to be selectively moved in a coaxial direction by the user to disengage the pull release and the protrusion. The pull release can also be adapted to rotate or swivel around the protrusion.

The invention relates to a system comprising: a foundation element that has a universal joint, wherein the universal joint has a first universal joint element connected to the foundation element for conjoint rotation and a second universal joint element which is rotatable about the longitudinal axis of the first universal joint element by carrying out a rotation about its own longitudinal axis; a floating wind turbine; and a mooring line. One end of mooring line is connected to the foundation element a first connector connected to the second universal joint element for conjoint rotation and the other end of which is connected to the floating wind turbine a second connector rotatably mounted on the floating wind turbine. The system also includes a controller which, on the basis of the rotational position of the floating wind turbine about the foundation element, brings about the adoption of a rotational position of the second connector rotatably mounted on the floating wind turbine; wherein the rotational position of the second connector rotatably mounted on the floating wind turbine corresponds to the rotational position of the second universal joint element about its own longitudinal axis, which rotational position geometrically corresponds to the rotational position of the floating wind turbine about the foundation element.

Described herein are examples of stiffening shafts, which in some cases are adapted to couple to a marine vessel. An exemplary stiffening shaft can be used to extend a motor from the marine vessel or be used as a shallow water stick anchor. The exemplary stiffening shafts can include a plurality of linked vertebrae stacked to form a column and at least one inelastic tension element threaded longitudinally through the plurality of vertebrae. The shaft can have a flexible configuration when the at least one tension element is released and a stiffened linear configuration when the tension element is tensed to react to torque and bending moments. Alternatively, the stiffening shaft can be used as a shallow water stick anchor for a marine vessel by piercing the bottom of a marine environment (e.g., a sea bed, a lake bed, a river bed, etc.).

An arrangement for mooring, loading and unloading of a vessel, includes a structure connected to the seabed and a Y-formed yoke for connecting the vessel to the structure, the structure including a stationary inner element adapted to be fixedly connected to the sea bed and an outer element having a rotatable fastening to the inner element, the outer element having a connector for fixing the yoke, wherein the yoke is provided with a pitch articulation to fix the first or mutual end of the yoke to the connector of the outer element and a roll articulation positioned between the pitch articulation and the first and second leg to allow the legs to rotate along the longitudinal axis of the yoke with respect to the pitch articulation.

An apparatus and methods according to the present invention provides a human powered catamaran-styled watercraft and methods of configuring and operating the watercraft. The watercraft generally comprises at least one hull in communication with a folding collapsible frame, wherein in the frame comprises a center rack pivotally joining hulls of hull sets to provide for common pivoting of the hulls during articulation of the watercraft, thereby the hulls and frame are in further communication through a at least one pivot pad which provides for slidable pivoting of the hulls during articulation of the watercraft. A method of folding and reversibly extending the watercraft to provide for optimized storage is provided. A method of operation of the watercraft to provide for articulation of the watercraft is provided.

According to the invention an energy conversion system, in particular a solar park, is proposed, which is configured to be arranged floating on a body of water, with at least three floating units (48a, 48b) and with at least one connection device (66), wherein the connection device (66) connects at least two floating units (48) in a rigid manner and/or at least two floating units (48a, 48b) in a movable manner.

A watercraft assembly is configured to provide an area protected from splashing water and sunlight. The watercraft assembly has a kayak with an open bow. A canopy assembly attached to the open bow. The canopy assembly further comprising a lower rod attached to the bow with a line clamp. A mounting bracket assembly is arranged above the line clamp, and joined to a small rod and a large rod. A canopy tarp is arranged over the lower rod, the small rod and the large rod wherein the canopy tarp covers a protected area protecting the protected area from water splashing and sunlight.

A mooring device for a wave energy conversion apparatus includes a three-dimensional beam structure which houses the wave energy conversion apparatus and which includes two elements for rotoidal coupling to the energy conversion apparatus by wave motion spaced apart and defining an axis of rotation for the same apparatus. The device also includes an anchoring component fixed to the three-dimensional beam structure.

A watercraft mooring system comprising a plurality of interchangeable mooring members for the temporary mooring of one watercraft to another watercraft or one watercraft to a stationary object such as a dock. The interchangeable mooring members comprising connecting rod member embodiments with adjustable lengths and connecting rod members without adjustable lengths, vacuum-handle member embodiments that provide an initial vacuum and a continuous vacuum to one or more vacuum cup assemblies, and a cleat connector member embodiment that is interchangeable with a vacuum-handle member.
