Here are another Cruiserlog threads about this topic:
Why are you wanting to do this? If you're in a warm location, you can do all that while the hull is in the water. The only reasons to beach the boat would be to do something which requires "dry" like painting, change a thruhull or something with a prop shaft. Are you sure you want to do so just to clean and do anodes?
Anyway, it really depends on your keel, as well. Ours is wide so the boat can settle down onto it (It is 14" wide aft and narrowing to 11" before becoming the forekeel area which is only about 6" wide.) If the keel is narrow or of a modern design, you may never successfully do it. So--what is the keel like?
For a tradition full keeled boat, you can get yourself some boat legs or make some. They are attached to brackets or to the boat's chain plates. Tricky to use, but many folks have used them. We have not done so though we know the designer of our boat was known for making sure his boats could use boat legs--therefore we assume there's a way to do so with our boat--we just don't know exactly how.
Here's a pic of a boat circa 1950 using boatlegs:

Here's a company that makes boat legs:
The Yacht Leg and Cradle Company
Here's a design by Gartside for Gartside boats:
Gartside Boats | Beaching legs, Design #131/8
Final thought--you might go back to the designer or builder of your own boat and ask for a boat leg design to fit.
