Cycling home from my pal Penelope's this afternoon, I glanced to my left and saw this monstrosity. If it's midway between Southend and the Isle of Grain, which is the direct line from where I stand but it's too murky to be able to see, it must be about 3 miles from my vantage point in Ambleside Drive. The furthest building in shot is about half a mile away from me.
It's the HMM St. Petersburg, apparently, one of the same class of container ships as the the HMM Algericas, which is the largest in the world, and which also occasionally visits the Thames. Each holds somewhere in the region of 20,000 large containers.
