Hobie's Anchor Trolley Kit (fits the Pro Angler) includes everything you need to complete the installation. Hobie has made it easy by designing a kit that doesn't require thru-bolting to mount cheek block pulleys and pad eyes. Effectively position your kayak just how you want it in any condition or depth of water. Adding an anchor trolley to your kayak lets you easily deploy your anchor, drift chute or stake out pole over the side of the cockpit area, then move the attachment position forward or aft to hold your boat in the position desired. Easily sit facing down stream / wind at anchor. Simple pulley system and cleat allows adjustment all along one side of your boat anywhere from bow to stern.
