Let me post something contrarian. Both are true stories.
1. A plans to go out sailing one day and is about to untie his docklines and leave the slip when something comes up and he has to go home. He unclips the mailsail halyard and ties it off to the side, where it always is. Its not that windy so there is no halyard slap at the time.
B is a liveaboard
in the marina and that night hear the halyard making noise
on A's boat. He unties the halyard, wraps it around a spar then through a spreader, and reattaches it to where it was. Now, the halyard is quiet. But, unless you look very closely, you would think nothing has changed.
The next day A, unawares, attaches his halyard to the head
of the mainsail
,and leaves the slip. He points into the wind
, and raises the halyard. Or tries to. It goes up halfway and gets tangled. A barely avoids crashing into the breakwater.
A had no reason to think someone would board his boat and move his halyard.
If you don't like the way someone has arranged their lines, and you take upon yourself to change it, have the courtesy to leave a note.
2. C is a relatively newer sailor. He cleats
his docklines on his sailboat. But not exactly; he ties the dockline to the cleats
with two half hitches. His neighbor D on the marina boards his boat to cleat the boat "properly. " C has no clue as to what has gone on and wonders what else has been changed. Why was this done? what mischief is up?
