I do it as follows but at risk of stating the obvious this method only works with an offshore breeze & swell direction.
Pick your anchoring spot, stop over it and check depth of water.
Neatly flake out the required length of anchor warp on the deck of the boat and make fast to your cleat.
Attach a really long, non-floating line to the crown of the anchor as your shore line. If you have a small kedge anchor, attach it to the end of your shore line as your beach anchor
Place the anchor on the bow tube
Motor direct to the beach, engine off & up, don't forget to take the keys out! Take the end of the shore line with you.
Give the boat a really good shove back out to sea whilst paying out the shore line.
When the boat reaches your anchoring point, give the shore line a good tug and "plop" your anchor will fall over the side with the warp paying out behind
Wait for your boat to settle onto the anchor and retreat up the beach with your shore line to looks of "he's don't that before...." from the other less dry boaters on the beach
To recover, just pull in the shore line anchor and warp until your boat arrives on the beach
