See if you can put a LED anchor light on, check the shelves for ware, straighten the windex or vane, check all the rigging, maybe rig an extra line or messenger cord, check your spreaders and mounting, maybe put a deck light on. There's plenty of work to do. I used to tell the manager of a boat yard I was in that they should half the charges for dropping the mast and raising it. They'd find so much work they'd make the money back and more. They would complain there was no money for them in sailboats.
