An underwater propulsion system is disclosed comprising a foot board with one or more battery-powered propulsion units. A throttle control system may be enabled in the foot board such that a movement of the user's foot controls the throttle. Flattened Lithium batteries allow thin lightweight construction of the foot board. Use of trolling motors as propulsion units provides thrust advantages over pre-existing underwater scooters.

A personal safety flotation device which can be carried on a person for an evacuation requiring entry into a body of water. The personal safety flotation device is for individual use comprising a carrying bag and an inflatable platform which is stowed in the carrying bag in a deflated state. The inflatable platform has a hexagonal shape allowing stability on the water and ability to connect to other inflatable platforms to create a larger surface area. The inflatable platform comprises additional safety features such as an emergency radio beacon, LED lights, light reflective strip, radar reflective pad, rope around a perimeter, and spring hooks for attachment. The carrying bag is attachable to a person and upon entry into a body of water the inflatable platform is automatically inflated with a connected compressed gas cylinder and the inflatable platform remains connected to the carrying bag via a connection strap.

A collapsible transom for an inflatable raft has a front section including two parallel front struts and a rear section including a floor portion and a collapsible support portion. The floor portion includes two parallel rear struts, and the two parallel front struts and two parallel rear struts are slidably connectable to each other by insertion into tubular end portions. The support portion is pivotally connected to the floor portion and movable between an expanded position with the support portion substantially parallel to and spaced away from the floor to a collapsed position with the support portion adjacent the floor.
