BoatTector's Complete PWC Screw Anchor Kit is perfect for anchoring your PWC in the shallow water just off the shoreline! The anchor's clever design spins down into lakebeds and riverbeds for a secure hold. The kit includes a 7' anchor line with large snap-on hooks for easy connection, a highly visible marker buoy to float just above your anchor, and a durable padded nylon storage bag to keep the kit contained and your PWC protected while bouncing around on the water. Screw anchor systems work best in 2' to 3' of water with mud or compressed sand bottoms. Not designed for unattended anchoring. Do not use for long term or overnight anchoring.
