No one here has a problem with a boat in peril being boarded, and lines being adjusted or added, or halyards tightened or tied off if required. It's neighbourly boatkeeping, that keeps us low on the marina's radar. the more we tend to ourselves, the less we have to worry about the redshirts sending nasty letters about additional dinghies and kayaks or unapproved dock improvements like beer pong tables and umbrellas.
Precisely why we take care of each other, and only if absolutely necessary will anyone board somebody's boat, even though the marina guy is awesome, but he's getting old, and he hurts a lot, from war injuries. .. however, there was this one time last year, somebody helped themselves to my BBQ gas off the back rail and left me a nice set of sunglasses in the cockpit. Well worth the price of a small canister of propane.
