Ship RP rules

[busyrobot]

I would like some clarification on the RP rules as they apply to ships.

I imagine, going to a Kingdom and smashing up all the boats is on the don't-list, what is there more general rules?

Also, what is the etiquette around possibly abandoned ships-in-progress on the main island?

I wouldn't want to steal someone's ship-to-be, but sometimes a bunch of newbies just start a ship for fun and change their minds to off and grow corn or something.

Any other RP etiquette that people would like to mention (vent about) that don't apply to ships would be worth noting too.
