This type of anchor quickly sets in most seabeds. It has a high-strength design, a good holding power and veers well due to its roll-stabilized design. It acts like a grapnel in rock and coral. The only drawback is that it is difficult to stow unless in rollers or chocks. It has a limited holding power in mud.
