I last owned a knarr for about a week in world 9 before the world ended, so I am wondering what is the current advice around owning them.
Keys
You can install a lock on a knarr. What does this do? Does it prevent people from opening the cargo, or does it only prevent people from moving it? Does it matter whether you make a slave key or a master key? I have also heard that common practice is to drop your key in the water if you are attacked. Depending on whether you can still move the knarr afterwards, doesn't this put you at a high risk of drowning after a KO?
Docks
I've never built a dock. Is there anything not so obvious about it? Can knarrs only dock on a certain side of it or something like that? I think porting back adds to travel weariness? So you can't port back if your weariness is too high? Does quality matter? Can docks be destroyed by hand? Can knarrs, for that matter?
