The Scotty Anchor Lock with Mount is an anchor release system for small boats in still-water fishing situations. Easy lock and release action allows anchor line adjustments. For use with rope up to 1/2" diameter. Tough construction and roller bearing for smooth, quiet operation. Choose between combination deck mount or flush mount.
I have not used this yet, but so far it appears to be a well made, thought out product
I have installed these on a number of kayaks and I find them way more efficient and convenient than any other anchoring method including stake out poles. I put a mount on each side of the kayak close to where your feet would be and that eliminates about 90% of the time you have to use the anchor trolley.
