Und,
Check out the Lemar claw anchor.
When you stop down to the marinas and check out the river boats at the docks on the Mississippi river for the bigger 20-50 foot boats, nearly everyone of them have a Lemar Claw Anchor on their Anchor Davit.
Pick the one that will hold your particular boat and you will be good to go.
This same design, in a much larger size are used to hold huge boats in place on the ocean.

When using any anchor, attach at least 4 feet of 3/8th link chain to the anchor and then use an anchor clevis to hold the nylon rope with a braided in anchor thimble on the end that you run the bolt of the anchor clevis through to hold the chain on the end of the anchor rope.

--------------
If you mount an anchor anchor roller at the front edge of your boat, it makes it very easy to lower and lift your anchor. Then, drop the pin in place that the pin will secure the anchor in place.
