Roller Grapnel

Abstract

The present invention provides an improved grapnel which permits towed arrays to be retrieved more easily and with less chance of damaging the array. The invention includes a pair of U-shaped members attached to a center stock, the U-shaped members being attached in a perpendicular relationship to each other. A threaded rod connects each vertical portion of the U-shaped members to the center stock, and each row has a roller disposed thereon. The grapnel further includes a hub disposed on the center stock proximate the rollers and ramps respectively attached to each vertical portion of the U-shaped members, for guiding a towed array into engagement with the rollers.
