Mooring tensioning arrangement (10) on a vessel (60), comprising a moonpool (20) having a through miming vertical channel with an upper moonpool opening (22) in proximity to a deck (62) of the vessel (60), and a bottom moonpool opening (24) open to surrounding sea (30). A winch (14) is located above the moonpool (20), wherein a first anchor wire pennant (42) runs from the winch (14), over a stern (64) of the vessel (60) and into sea (30), and a second anchor wire pennant (46) runs from the winch (14), through the moonpool (20) and into the sea (30). A wire/chain stopper (18) securing the second anchor wire pennant (46) is placed in the moonpool (20), and the bottom moonpool opening (24) is curved to match bending 0radius and to provide a transition in direction of the second anchor wire pennant (46).

A kayak anchor support system includes a first support arm having a first end opposite a second end, wherein the first support arm is removably securable to a kayak via at least one mounting bracket. A proximal end of a second support arm is affixed to the first support arm adjacent to the first end. The second support arm extends orthogonally from the first support arm such that a distal end of the second support arm is maintained in an elevated position above the kayak. A pulley is affixed to the distal end of the second support arm. An anchor cable is engaged with each of the pulley and a reel, wherein the reel is disposed opposite the pulley. An anchor is affixed to a terminal end of the anchor cable, whereupon actuation of the reel, the anchor is selectively movable between a raised position and a lowered positioned.

A cylindrical receiver has an upper region with female screw threads, a lower region, and a centrally located washer. A cylindrical sleeve has an upper end with male screw threads threadedly coupled to the female screw threads of the receiver. A cylindrical passageway is formed between the receiver and the sleeve. A cylindrical stake is slidably received in the sleeve. A tether line couples the stake to a movable patch whereby when the movable patch is coupled to a fixed patch, the stake will be in a raised orientation and whereby when a user separates the movable patch from the fixed patch, the weight of the stake will lower the stake into a lower orientation into a sandy or rocky bottom.
