This invention provides a compact and simple mechanism for retrieving a submerged weight attached to a rope and eliminates significant manual effort using a simple yet effective camming device that facilitates belaying of rope in many situations and in particular to facilitating the raising of a submerged weight by the action of the associated water craft, without additional motors or drive mechanisms. The guiding frames interacts with the cam block to allow rope to slide in one direction towards the boat, and for selectively preventing the rope from moving backwards. |
