I haven't looked at the murrays anchor but I anchor my boat all the time instead of dragging it up on the beach. Check out west marine. Guardian, (The slighty cheaper version of fortress) Has a 4lb anchor thats light and small. It folds but you have to lossen two small bolts to do so. I carry mine under my tramp bag. You'll find the boat sits best at anchor with the main centered and lighty snugged up.
