It's a lake. Powerboats don't have our keel to contend with so they seem to have an easier time. Most powerboats I see are with two or more people, where one person will get the trailer while the other one circles around in the water until the trailer arrives. WHen I have sailing companions there isn't a problem because they can hold the boat off the rocks/concrete.
I looked up anchoring systems and one is called "clothesline anchoring." Maybe this is something I should think about? That, or just put a boatload of fiberglass down there (pun intentional). This would keep the boat off the ramp while I get the trailer.
