Abstract

A square bag (28) open at the top or front with holes (30) in the bottom or opposite end for drainage and flow through. Tow members (16) secured to the periphery of the bag (28) at the open end of the body in a hinging fashion so they can be neatly folded down in the bottom of the bag (28). The anchor rode (10) is secured to these tow members (16) and faked down into the bag (28). Battens (32B) and reinforcing material (20) are used to force the bag (28) to stand up in the open position facilitating ease of feeding rode (10) in and out of bag (28). Tow members (16) hinge outward and Batten Reinforced Anchoring Bag (35) becomes a sea anchor when thrown overboard. Holes (30) in bottom of bag let water flow through bag (28) somewhat slowed down, facilitating in bag (28) staying open and creating drag which is the object of the sea anchor. Through hole ( 26) in bottom of bag (28) is provided for tripline (36C) to haul Batten Reinforced Anchoring Bag (35) back to boat (33A) and provide, in conjuction with ring (12) at eyelet (14), a means for using two Batten Reinforced Anchoring Bags (35) at once as sea anchors.
