A watercraft self-rescue reentry device configured to facilitate a reentry of a user into a watercraft is disclosed herein. In one or more embodiments, the watercraft self-rescue reentry device includes at least one pole member, the at least one pole member including at least one attachment device for attaching the at least one pole member to the watercraft; a foot step coupled to the at least one pole member, the foot step configured to accommodate a foot of a user stepping thereon while the user is attempting to reenter the watercraft from water surrounding the watercraft; and a water anchor device coupled to the at least one pole member, the water anchor device configured to resist a moment applied to the at least one pole member by the user stepping on the foot step by means of the water anchor device being at least partially immersed in the water.

A lifesaving handle system for a watercraft surface such as, but not limited to, a boat hull. The handle system remains inside a cavity in an exterior surface of a watercraft hull when the watercraft is upright (i.e., when it is not capsized) such as when it is flowing on a body of water in normal operation. The handle may be rotatably attached to an interior surface of the cavity such that when the boat is upright, as in non-capsized operation, the handle hangs vertically in the closed cavity and is not within the flow of water passing along and around the watercraft hull when the boat is motivated on a body of water; and when the boat is overturned or capsized, the handle rotates out from the closed cavity under the force of gravity such that the grip handle is presented to a person in the water.

A flotation component, such as for a pull buoy, can be sized and shaped to be placed between the legs of a swimmer. The flotation component can include one or more features to assist in maintaining the flotation component in place while the swimmer is swimming. A pull buoy including the flotation component also can include an internally routed strap that assists in fastening the flotation component to at least one leg. A pull buoy including the flotation component can include a waist portion having a lateral diameter that decreases from one end to the opposite end.

In a rescue network system for a watercraft, a transmitter transmits a first distress signal of the watercraft to which it belongs. A receiver receives a second distress signal from another watercraft. An output outputs emergency information indicating the existence of the second distress signal from the another watercraft. A controller is configured or programmed to control the output to output the emergency information when the receiver has received the second distress signal from the another watercraft.

This application relates to flotation devices generally, and particularly to inflatable flotation devices configured for use by an infant to support the infant at least partially above the water and to at least partially retain the infant therein. In some embodiments, an apparatus is a flotation member having an inner perimeter, a top portion and a bottom portion. The flotation member has a first height between its bottom portion and its top portion at a first location of the flotation member. The flotation member has a second height between the top portion and the bottom portion at a second location of the flotation member, the second height different from the first height. The flotation member includes a support member at least partially disposed within the inner perimeter of the flotation member. The support member has a first portion coupled to the top portion of the flotation member at the first location. The support member has a second portion coupled to the top portion of the flotation member at the second location. The support member has a third portion between the first portion and the second portion, and the third portion is coupled to the bottom portion of the flotation member at a third location different from the first location of the flotation member and the second location of the flotation member.

A lifesaving handle system for a watercraft surface such as, but not limited to, a boat hull. The handle system remains attached to an exterior surface of a watercraft hull when the watercraft is upright (i.e., when it is not capsized) such as when it is flowing on a body of water in normal operation. The handle may be rotatably attached to a hinge attachment such that when the boat is upright, as in non-capsized operation, the handle hangs vertically and is not within the flow of water passing along and around the watercraft hull when the boat is motivated on a body of water; and when the boat is overturned or capsized, the handle rotates out from the watercraft hull under the force of gravity such that the grip handle is presented to a person in the water.
