Probably you will want to know who owns the beach that you are landing on.
I bought a H16 last year (one of the best decisions I ever made) and was launching it from the Edgewater boat ramp for the tail end of the summer.
The Edgewater boat ramps are part of the Edgewater marina in Cleveland Ohio.
The Ohio State parks have a rule about boating and swimming at the same beach. In general you can't. There has to be a special swimming and boating beach to do both. Just look for the people with the PWC's.
Edgewater park (different from Edgewater marina) is a bit west of Cleveland and they have a swimming only, and a swimming and boating beach. There is a jetty. West of the jetty you can sail up to the beach and park your boat on the beach.
Last year I took my 10, and 13 year old and sailed over to the beach (west of the jetty) for an afternoon of sand and picnic.
There is an Ohio Dept. of Natural Resources website:http://www.dnr.state.oh.us/facilitiesma ... fault.aspx
that explains about boating in Ohio State Parks and what you should know.
The other lakes, and states, and Canada. . . . Sorry, I seem to be at a loss.
