The EZ Marine Anchor puller block is the #1 anchor pulling device on the Columbia River. A true professional grade piece of equipment. Designed and tested in swift water below the Bonneville dam. Our unique design makes pulling your anchor a smooth, easy process. The EZ Marine puller block is attached to a buoy of a proper size to lift your anchor. Attachment is best with our SS, Eyebolt kit. The anchor line is threaded through the puller block after the anchor has been set. Just like that, you’re ready to pull. Simply power your boat around the buoy, steer your boat parallel to the anchor line until the ball lifts the anchor off the bottom and to the ball. When boat is stopped the anchor will be held under the ball.
