A man overboard system may comprise a strap system allowing for the rescue of a subject who is in a horizontal position. A strap system may comprise a loop 830 with an end of the loop defining a chest strap securing the chest of a victim and a one-way buckle 840 retaining the chest strap around the victim. A side of the chest strap may be attached to a main body strap 870 which may comprise a plurality of webbing tubing pieces 880 or a monolithic sheet of material to support the backside of the victim. An attachment bar 885 may be attached to the main body strap and a plurality of side straps 860. The side straps may be attached to a far end of the loop.

Networkable digital life jackets and associated methods are disclosed. An example life jacket includes a state manager and a swarm manager. The state manager is configured to selectively operate the life jacket in one of multiple operational states of the life jacket based on data obtained from one or more sensors of the life jacket. The swarm manager is configured to form a swarm network including the life jacket and one or more other life jackets.

Some embodiments may be of spearfishing apparatus fitted with at least one magnet configured to repel sharks away from the spearfishing apparatus. The spearfishing apparatus may be one or more of: a spearfishing shaft, a spearfishing tip, and/or a spearfishing gun. Some embodiments may be of personal floatation devices (PFDs) fitted with at least one magnet configured to repel sharks away from the PFDs. Some PFDs may be fitted with a tethered drop-down magnetic apparatus to protect lower extremities of a wearer of such PFDs. Such magnets may be electromagnets powered by batteries in some embodiments.

The invention relates to a novel pet flotation and safety vest device wherein the body section attaches firmly yet comfortably to the pet, and strategically placed mesh panels allow for water drainage. A padded chip strap also has mesh sections for drainage and a strategically located top grab strap that will keep the animal level when it is being pulled from the water. The underside of the vest also has a reinforced grab strap in the event an animal may be upside down in the water.
