Praise for The Shipwreck Decoder

‘The more you know about ship features, the better equipped you are to use components to navigate or “decode” a wreck… Strongly recommended.’— SCUBA Magazine

‘I would recommend it to any casual recreational wreck-diver, to budding archaeological divers and, I reckon, it could fill many a gap even in experienced wreck-divers’ knowledge. You won’t spend a better £20 for a dive-related book.’– Divernet.com

‘Most divers and archaeologists learn about the technology of ships piecemeal, according to the age and type of wrecks that they have been investigating. This can result in considerable gaps in knowledge – you might know a lot about cannons but little about steam engines. And yet the need for a comprehensive knowledge base is paramount, as both amateurs and professionals can move between wrecks of widely disparate characteristics. In this excellent book, Ashton East addresses this need with a wide-ranging catalogue of ship components and fixtures, written and illustrated with great clarity. Unlike most books of this nature, which tend to be weighty reference encyclopaedias, The Shipwreck Decoder is a compact guide that can be read over a couple of evenings. It should be read by all divers involved with wrecks and others with an interest in ships. It is a wonderfully useful book, and I cannot recommend it too highly.’– David Gibbins, Maritime Archaeologist, New York Times and London Sunday Times Bestselling Author.

‘I wish this book had been available 30 years ago when I learnt to dive. I have loved diving on and investigating shipwrecks since those very first open water dives in Portland Harbour, but for years never really knew what it was I was looking at. Now all new divers can. There are few books that are specifically targeted at helping divers get a better understanding of what lies on the seabed in such a clear way so this should become a mainstay in every diver’s library.’– Mark Beattie-Edwards, CEO, Nautical Archaeology Society.

‘I’m amazed how much information Ashton has managed to cram into two hundred pages – I’ve certainly learned a lot!’– Dominic Robinson, Deep Wreck Diver.

‘This is a fantastic book and just the kind of introduction to shipwrecks I wish I had when I started diving. Ashton describes it as a primer and a briefing aid to “read” wrecks, and I can definitely see readers leafing through the pages before and after dives to interpret what they’ve seen. I can’t think of another work that can gently guide the reader through the intricacies of ancient boat-building technology or the science that drives a modern marine engine. Its ambitious scope is wide ranging, tracing developments across historical periods and between cultures. While it doesn’t try to master every topic, it methodically covers every part of a ship you can think of from stem to stern (or bowsprit to rudder), with deep dives into important subjects when Ashton thinks the reader needs to know more. Like me you’ll probably find an interesting fact you didn’t know in each chapter. Hopefully it will inspire the curious diver to make sense of the jumbled parts of a shipwreck encountered underwater and enable readers to better appreciate the engineering marvels these ships once were.’– Giles Richardson, COO, Maritime Archaeology Sea Trust.

‘Thanks to this little gem of a book, that confusing pile of scrap on the sea bed will just make a lot more sense – you’ll know where to look for stuff, how to interpret what you see and maybe even find that illusive ship’s bell! For me, that makes The Shipwreck Decoder an essential and invaluable resource for any diver.’– Jason Brown, Bardo Photographic
