I personally use the anchor and float approach. Wrap the float around the fore stay or dolphin striker and the boat will point into the wind.

There is also the the Marstrom 4 wheeled Aclass cart. This was made for sailing from a solid rock Harbor and ramp. Wheel the boat out. Anchor the cart. Pull or sail the boat off. When you come back, put the boat on the cart, tie the boat to the cart and generally I tie the anchor to the boat. You can wheel it back or let it sit and take a break. The boat is really stable on the cart.
