+1 there are many good details in there.

When you land on a charter boat there is no limit to what you may or may not find. Good sail and rigging management is to always easy the load on halyards and sails when you are not using them. There is simply way to tell where the last person to touch a halyard left it relative to tension.

Some years ago The Moorings was plagued with masts falling over on the larger boats where no one had ever positioned and tuned the standing rigging properly. When the breeze, halyard, and vang tension showed up the mast simply fell over. As soon as the sail is unfurled the next proper strep is checking halyard tension. Then leads and leech cords. If the boat was put away properly? The halyard tension will be low. There is no reason to leave the expensive sail under tension sitting at the dock.

There is your 50 foot diaper in the making.
