Portable watercraft transfer device for disabled users

We will invent a portable, patentable device to assist in transfers to and from small watercraft that will be used by those with mobility impairments. Transfers with the device will require only one able-bodied assistant and will take no longer than three minutes. The device will weigh less than 40 pounds, cost approximately $400, and interface with a variety of docks and small watercrafts. Setup and takedown will each take less than five minutes and the device in its collapsed state will fit into a car trunk or a loaded two-person, 16-foot canoe.
