I am curious if there is actual relation between all nouns ending in -ship, such as relationship, citizenship, sportsmanship, etc. with the vessel for transporting people or goods over the sea?
-ship is added to a noun to establish status or condition.
For the hardcore etymologists who don't feel like looking this up and to complement the top answer, here's the etymologies of (-)ship from Dictionary.com.
