Blubbership

The Blubbership is so called because of a thick layer of bio-engineered tissue that surrounds it.
Blubberships form the means of Londinium to trade with the few other cities that exist in Europe.
Blubberships are exceptionally cost effective to make, as they can be retrofits of existing trade and battleships to survive in the contaminated waters of the oceans.
