I agree too, but the point is that with a cat you don't have to go into marinas. Watch most monohulls at anchor in any kind of swell and they roll like a pig driving owners into marinas. Cats don't. No need for flopper stoppers on a cat! Also depends where you go, and what you call a marina. Many ports welcome cats and don't surcharge. you can usually find a nice quiet bay to anchor in that deep keeled boats don't go. Fit a watermaker and solar panels and all you need is to go ashore for food and diesel. Welcome to the antisocial world of cat ownership!
