The carbon-fiber pole helps the Seascoopa open. Weighted line keeps the leading edge immersed underwater.

winch is often the easiest to use. One problem with sling-type de- vices such as the Lifesling is that the victim could suffer secondary injuries during a vertical lift. Risks of a verti- cal lift include: a semi-drownedperson ingesting more water, a spinal-injury victim suffering further injury during the lift, and a potentially fatal loss of blood pressure (particularly in a vic- tim suffering hypothermia). With care, these risks can be mitigated, but an ef- fective horizontal lifting device could be a boon to rescuers. MOB Recovery Gear Another drawback to the Lifesling and most other lifting devices tested at The Seascoopa fine-tunes the parbuckle the 2005 symposium was that they were ineffective with unconscious victims. for heavy lifting in a man-overboard rescue.
