A pulley system for tying a boat to an anchor comprising a block and tackle assembly and a jammer. The block and tackle assembly has a plurality of pulleys arranged on a first bracket and a second bracket, and a first rope strung sequentially through each of the pulleys, ending with a last pulley. The jammer is coupled to the second bracket and has a channel and a jammer exit at the end of the channel. The last pulley, the channel, and the jammer exit are configured to create a tortuous path for the rope through the second bracket. The channel may be misaligned with the last pulley. A swivel and a rope clip may be coupled to the block and tackle assembly. The swivel is configured to rotate at least 360 in either direction. The rope clip is configured to allow for quick tightening of the pulley system.

A maritime alignment and connection system allows a boat to be recovered and docked while a host vessel is underway. Components form a cradle to guide and slow an approaching boat into a desirable orientation such that the boat will be held in place in the cradle. Once captured, the boat can be locked in position to prevent it from inadvertently slipping its berth.

A pulley stopper including: a clamp portion that includes a bar-shaped upper clamp and a bar-shaped lower clamp; and a pair of fasteners that are disposed at opposite ends of the clamp portion to couple the upper clamp and the lower clamp. The pair of fasteners and the clamp portion are coupled such that the upper clamp and the lower clamp are fixed side by side through the coupling of the fastener and the movement of a belt disposed between the upper clamp and the lower clamp is stopped.

A cleat for mooring a watercraft at a thrown end of a line has a base surmounted by a body, the base being fastenable to a watercraft deck, the line having a rope and stopper formed by a transverse protuberance, the cleat having an engagement part adjoining the base and a funnel-shaped through-opening to an elongate slot in the body, the slot having a height allowing the longitudinal progression and transverse passage of the rope from the opening towards the interior of the body, the slot leading into a chamber having a minimum dimension greater than the minimum slot height, the maximum dimension of the chamber being less than the dimension of the protuberance forming the stopper so the stopper of a line passing transversely through the body can be blocked against a the body side face both with the rope in the slot and in the chamber.

Disclosed is a tugboat 1 for assisting a marine vessel 2 to manoeuvre. The tugboat 1 comprises a hull 11 having a perimeter P. The tugboat 1 also comprises a line handling system 10 comprising a line guide mechanism 100. The line guide mechanism 100 is movable relative to the hull 11 to an operation position, at which the line guide mechanism 100 is for guiding movement of a portion of a line 13 of the tugboat 1 towards a predetermined region R of the perimeter P.

A vessel attachment device includes a body, first and second attachment arms, a biasing member, and at least one line connection interface. At least one of the first attachment arm and the second attachment arm is movable relative to the body. The biasing member is configured to apply a biasing force at the at least one movable first and second attachment arm to bias the at least one movable first and second attachment arm to an open position. And, the biasing member is configured to selectively release the biasing force and apply an actuation force at the at least one movable first and second attachment arm to move the at least one movable first and second attachment arm from the open position to the closed position to attach the vessel attachment device to a vessel attachment point.
