I think the peeps who had their ribs nicked from Bembridge Harbour a while back (5 as I remember in one night) would disagree with you. They were just hot-wired and driven out of the harbour.
If the insurance approved chains are as heavy as the one I use on my motorbike then you'll need an extra 25HP to carry the bloody thing about.
Only thought that occurs about chaining up in a marina - if the staff need to move your boat in a hurry( e.g. an adjacent fire or somesuch) they won't be able to or won't bother to.
