My Maine Coon cat likes to jump on my Persian.?

I have a maine coon cat who is about a year and a half and a persian who is three. My maine coon is always jumping on the persian, he is 16lbs and persian is 4lbs. The maine coon has all his claws and the persian has just his back claws (shelter cat). I am scared the maine coon will hurt my persian. He has never scratched or bit the persian. I have tried everything to make him stop, water bottle, loud noise etc.. Any suggestions?
