I'm fascinated by the suffix -ship and while it theoretically has no connection to the noun "ship", all definitions provided by Oxford Dictionaries seem to in fact not be terms that would be out of place on the deck.
There are a great many words which end in -ship and I wonder if this suffix might not in fact truly be a vessel with some cargo of mysterious treasure held within. In my personal life I often create new words and have become fond of the idea of creating new types of -ships. I do not prefer relationships and friendships over extraordinaryships.
I'm shocked at how difficult it is to construct new -ship words and I would like to learn about the factors that influence whether a word can be suffixed with -ship.

The etymology of this suffix is given at length by the OED -
The important part of that is perhaps the meanings of creation, creature, constitution, condition.
Five separate nuanced senses are given but they are all clearly related, meaning the state or condition of being. Examples of each vary from 1.adjectival, DRUNKENSHIP, HARDSHIP, WORSHIP 2. added to nouns FRIENDSHIP, LORDSHIP 3. Designating person of rank REEVESHIP 4. State of life, occupation or behaviour CLERKSHIP, COURTSHIP, 5. Added to nouns forming compounds TOWNSHIP (this is the only modern example given, and I don't fully understand the distinction from 2.)
I am not sure if this answers the question, but it does provide some etymology, and the manner in which the suffix is used. Further words I feel sure could be created if they fell within one of those categories, and there are plenty more in everyday use e.g. ACQUAINTENCESHIP. But how about DRIVERSHIP e.g He handed over to another member of the party the drivership of the vehicle?
