Last year was my first year with my 180. We beached it some because it had been beached previously (I bought it used). The biggest issue I had was if the motion of the water pushed the stern sideways, causing it to be sideways to the beach rather than nose-in. I got a rope and one of those corkscrew type hooks (like the kind you might use to connect a dog to) at Home Depot. I hook that to the bow loop (where you attach the chain from the trailer). Now, I've got an anchor for the stern. If you're going to beach, I would recommend these because then you don't have to push the boat so far on shore that it will be tough to get it off again and you won't have to worry about the stern coming around sideways.
One thing to be careful of, though: make sure the beach is soft, or you'll scratch up the bottom of your boat.
