Use a longer painter, but put a pool noodle over the line (slice it and secure it with zip ties) so that it floats; otherwise you will get the painter hopelessly tangled in the hardware at the bottom of the mooring ball. As a general thing, I prefer the soft round rubber (I think they are made in Norway??) mooring balls to the hard plastic ones because of noise and hull damage. I was harbor master here in Maine for a couple years and that is the solution we use. Just putting a pool noodle over the painter might do the trick as it will keep the ball somewhat away when the tide or wind is not strong enough. FWIW.
