If you wanted, you could get one of those stretching anchol lines, set your anchor, back the boat into the beach to unload while someone holds the boat in place, then tie a second line to a rear cleat and allow the stretching bow anchor line to tighten back up, pulling your boat from the shore towards the bow anchor. Then, set the rear cleat line with another light anchor on the shore. When it is time to go, reverse the process....pull the rear cleat line rope to pull your boat back towards the shore, hold the boat in place, load the folks and the gear, last person stops holding the boat, the boat goes back towards the forward bow streatching anchor......ya pick up the anchor and go. This also helps when folks are in the area boating, which seems to be an issue....to give you space between the boat and the beach to enjoy the water. ....and...keeps your boat from bouncing on the bottom from the wake of the other vessels using the same area.
Could not find it in West Marine, but did find it for $$27.99 called Anchor Buddy Anchor line on page 63, part number 33367 in my Overton's Catalog that has just arrived. Says each one stretches from 14' to 50'.... so ya might want two of them linked together depending on how far from the beach/shore line ya want your boat.
