Abstract : The concept of a free-fall type of anchor that could be rapidly and surely placed and used to secure small to moderate size objects such as buoys, floats, and barges on station in great depths of water was investigated. Two experimental anchors were designed and tested. Major problems were encountered in (1) achieving adequate velocity through the water which resulted in a lack of adequate penetration into the bottom; (2) in accommodating the anchor line; and (3) in maintaining weight, size and proportions within practicable bounds. Consequently, the free-fall anchor concept as it applies to specified objectives and criteria was found to be not feasible. However, the anchor fluke designed for one of the experimental anchors and the method used for anchor line payout during its free-fall placement are considered worthy of further investigation in conjunction with other contemplated operations.
