Grapple Hook

Elastec’s Grapple Hook may be used for a variety of purposes, including the retrieval of containment boom trailing from a BoomVane. Take the grapple assembly and set the stop (the poly washer on the 3/8” rope) so that the grapple, when thrown into the water, rides slightly below the surface. The grapple should NOT extend all the way to the bottom, because if that were the case it could easily be snagged on an object in the river bed.

Cast the grapple into the water, while holding the other end of the 3/8” line. When the grapple snares the rope extending from the boom, pull it in and secure the boom to shore as desired.
