I have only very brief experience from once owning half of a 15 foot fibreglass runabout fixer-upper, but if you've got a 30 foot yacht then can't you just stick it on a trailer yourself? I feel like you're imagining a much bigger craft.

On top of that, dry docks are a common free amenity in boating/fishing towns, just using the tide to do your dirty work.
