My 28ft bilge keeler bounces around a good deal when the tide has moved to
be settling or lifting the boat.

Not only does it get damn noisy but it can get a bit frightening when wind
& wave combine to cause it to pitch up on one keel. But thats not my main
worry, I'm more curious to learn from folk who permanently moor in the
shallows and effectively have their boat on the dry once or twice a day.

Does this long term bouncing about cause any strutural damage? I'm
thinking it cant be doing my radar dome any good either.

I've just done an ad-hoc solo 2200mile voyage from southern New
Zealand to north Queensland. Conditions went as bad as 55knot gales with
7m seas the boat handled it a damn site better than I did.
