That's my point. Rudders come off with one pin (each) on my boat. Not worth taking a chance leaving them on the boat for long-term storage. Same reason I wouldn't leave the sails tied to the tramp.
The other thing is, even if the rudders aren't stolen, they are highly likely to be tripped over and broken at night (or even in daylight by people playing on the beach, not watching where they're walking, etc.) . No mischief needs to be intended for this.
Don't get me wrong, I wish none of this were necessary, but we don't live in that world...
