Anchors and Trolleys are incredibly important accessories for any kayaker. They should always be a part of your gear kit. An anchor is a relatively simple piece of gear. It is a large metal structure, typically with prongs, weighted and attached to a rope connected to your kayak. The weight and the prongs are used to catch the ground and weight the kayak so that it doesn't move from a spot. Anchor and trolley systems are great for kayak fishing since they keep the kayak in a single spot without the kayaker having to paddle constantly.
