Abstract: A safety apparatus safety apparatus for use with a sheave has a first plate suitable for placement over one side of the sheave, a second plate suitable for placement on an opposite side of the sheave, and a carriage positioned at a periphery of the first and second plates. The carriage extends across a gap between the plates. The carriage is movable along the peripheries of the first and second plates. The carnage includes a first carriage and a second carriage which are independently movable with respect to each other. The carriage includes a first body, a second body, and a discoidal member pivotally mounted to the first and second bodies. The discoidal member has a hole suitable for allowing the cable of the sheave to pass freely therethrough.

Abstract: A system for directing actions of a helmsman of a lifeboat has a lifeboat with a connector at opposite ends thereof, a shackle sensor cooperative with each of the connectors so as to sense whether the shackle is engaged or released from the connector, and a display positioned within the lifeboat that is cooperative with the shackle sensor so as to provide the helmsman with a visual indication of the engagement or release of the shackle from the connector. Each of the connectors has a hook pivotally mounted thereto. A hook sensor is cooperative at the hook so as to sense whether the hook is in the open position or the closed position. Water sensors are mounted to the lifeboat so as to sense whether the lifeboat has contacted a surface of the body of water. The various sensors are cooperative with the display so as to provide the helmsman with a sequence of operations during the use of the lifeboat.

Abstract: A safety apparatus has a sheave with a surface extending circumferentially therearound, a first housing interconnected to the sheave, a second housing interconnected to the sheave and pivotally connected to the first housing, and a line extending over the surface of the sheave and through, an inferior of each of the first housing and the second housing. Each of the first and second housings has a hole formed at an end opposite the sheave. The line has a first portion extending through the hole of the first housing and a second portion extending through the hole of the second housing. Bushings are respectively received within the holes of the housings.
