Varying implementations of adjustable marine fender holders are disclosed, which may receive a length of rope and hold it in place so that a marine fender may be adjusted to a desired height and then fixed in place without having to untie or retie the length of rope. Holders include a friction fit feature for engaging with a nautical cleat, and a rope channel through which a rope may be passed so that a proximal end of the rope may be wedged into a set of teeth or ridges to hold the rope in place. Another holder includes a single wedged arm that may be wedged underneath a cross bar of a cleat. Yet another holder includes a collapsible friction pad that may be wedged into a cleat. Yet another holder includes a compressible friction pad that may be wedged into a cleat.

An underwater connector for connecting a chain under water. The connector includes a connector body having a first end with an anchoring point and a second end for the anchoring of the chain. The second end includes an inlet opening that is communicated with a housing in the connector body, the housing configured to house an end link of the chain. The connector also includes a locking plate that is moveable from a first position outside the housing of the connector body and a second position inside the housing of the connector body. When the locking plate is in the first position an end link of the chain is allowed to pass through the inlet opening and into the housing of the connector body. When the locking plate is in the second position the locking plate contacts the end link to lock the end link inside the housing.

An anchor winch system includes an end effector, a guide channel, a winch, a cable and an anchor. The anchor winch system enables a user to deploy an anchor that is stored within the C or Z channels of a pontoon or tritoon boat. The end effector is mounted onto an end of a boat crossmember. The end effector is a holding apparatus that retains the anchor in a stowed position when not deployed. The guide channel traverses through the boat crossmember, and the cable is threaded through the guide channel. The winch is tethered to one end of the cable and the anchor is tethered to the opposite end. Thus, the winch is able to deploy or retract the anchor by paying out or reeling in the cable.

A releasable connection system for watercraft with first and second magnetic members configured to attract each other and releasably lock together through a male-female coupling mechanism. Watercraft can be connected to the first and second magnetic members through apertures with rope. A pivotable release arm releases the male-female coupling mechanism when rotated. Rope can attach to the pivotable release arm through an aperture. Connected watercraft can be released when a user remotely pulls a rope which rotates the pivotable release arm.
