Thirty Fathoms Deep

Rate this book
Bob Porter wants more from his life…

Stumbling across some aged parchment in a local bookshop, an idea strikes him.

The parchment is seemingly a journal that belonged to Don Jaime. The Captain of the sunken Santa Cruz.

The Santa Cruz was sunk in battle 350 years prior. But what of the treasure she was reportedly carrying?

Persuading his uncle to fund the search, he acquires a ship and crew to aid in his search.

Whilst most find this venture to be pointless and doomed to failure, Bob is determined that he will literally strike gold.

Weeks of searching the area indicated in the journal, he loses faith in his plan. Until one last tactic hooks the big fish.

Divers are deployed, plans are made and excavation begins.

Little does Bob know, this is not going to go as planned.

Each time the divers descend, they are risking their lives. Delicate equipment, storms, unforgiving terrain and a submerged wreck are sure to make this voyage dangerous.

But when his crew are acting suspiciously, Bob must wonder whether they are as trustworthy as originally thought.

Can Bob keep this salvage secret? If the Peruvian government hear of his find, they will claim ownership and he will lose it all.

With the nature of this trip kept secret until the wreckage was located, surely he has nothing to worry about?

But when company arrives, he soon realises that the government is the least of his worries.

Can Bob successfully salvage the hidden treasure from the depths of the sea? Will he be able to return home as a rich man?

Or will he and his crew perish to the secrets of the sea?

Thirty Fathoms Deep is a brilliant adventure novel, packed with action from beginning to end.

Rear Admiral Edward Ellsberg returned to active service with the navy the morning after Pearl Harbour, after a life of hazardous adventure in salvage operations, during which he won the United States Navy’s Distinguished Service Medal. He thereby became the first man to gain the award in peacetime. At Massawa he raised the two Italian Floating Docks, in spite of expert opinion that it was impossible. Later he served as Principal Salvage Officer under General Eisenhower in North Africa and afterwards in the Normandy Invasion. Rear Admiral Ellsberg was awarded the C.B.E. by His Majesty King George VI, and two Legions of Merit by the United States Government.

I enjoyed reading this book; it was a fun, light-hearted romp involving a search for sunken treasure, various dangers and difficulties involved in an underwater salvage, and pirates. There are a couple of moments in the book that are a 'sign of the times in which it was written' involving the captain's steward; fortunately, they are few and far in-between. There was not much character development; it was written for both adults and teenagers/young adults, so it is fairly simple in terms of the characters and how they interact with each other. It is an 'all-male cast and crew,' so there were no women in the book at all.

I found it funny that I kept thinking of the "young hero" as being a teenager when he is actually either a college student or has just graduated from college. I found myself continually reminding myself he was older, that he was no longer in high school.

One other thing that struck me as "funny" was how Murphy's Law was in full effect. I have not read any other books about underwater salvage, so I do not know how often problems occur, especially at a time when it was still a fairly new process with the technology available at the time. That being the case, it seemed like just about anything that could have gone wrong, did go wrong, with the divers while they were working underwater. "Something happened" to each of the divers that was life-threatening.

That was not the only 'thing' that I found funny.

It was well-written; it was pretty clear the author 'knew his stuff' (based on his life experiences) and it came across in the technical details of the novel. It held my interest throughout the entire novel, and it was also informative in terms of how underwater salvage operations may or may not have transpired during the late 1920s and early 1930s. It was a fast read, and I enjoyed reading it.

Rollicking adventure tale complete with pirates and looted Aztec gold.

First published in 1930. Disappointingly, but not surprisingly, there are a few uncomfortable racist terms. Cringeworthy, the dialogue given to Fitz, the only African-American on board the ship. A steward.

Guess the few politically incorrect portions were a sign of the times during which it was written and initially published, but it still made me squirm with discomfort.

Hazardous diving sections quite brilliantly described and rather nerve-wracking. A good reminder of how far we've come technology wise. And socially.

Will be reading more. Have a couple of the Commander's books sitting waiting to be opened.

Ellsberg's novel is dated, but it was written before WWII. If you can't stand the reality of the way hard men spoke in those days, don't bother reading it - you'll wet your panties. Other than that, the story is simple and exciting. Ellsberg comes by his knowledge of salvage operations honestly - he was Eisenhower's head salvage man in North Africa and played a critical role in the Normandy invasion. Read anything and everything you can find by this true American Hero.

A diving text book

The story was light as designed for fourth grade readers. Not much intensity or intrigue with simple characterization and a feel good ending.
