Author Horatio Clare joined two container ships for voyages that led to the recent publication of his book 'Down To The Sea In Ships: Of Ageless Oceans and Modern Men', available from Amazon for Kindle, or as a hardback. For millennia, the seaways have carried our goods, cultures and ideas, the terrors of war and the bounties of peace - and they have never been busier than they are today. But though our normality depends on shipping, it is a world which passes largely unconsidered, unseen and unrecorded.
