So many of the pleasures of recreational scuba diving don't exist for the deep wreck diver. It's not beautiful scenery for the most part; in fact, it's usually very dark. It's physically burdensome. These guys carry almost two hundred pounds of equipment, and should any of that equipment fail, they risk death.
There is pressure when you have a very big book like 'Shadow Divers' to follow up with something big. But you can't let that pressure determine what you do. You just look for the best stories, and when you find a great one, you tell it.
For my new book 'Pirate Hunters', I follow John Chatterton and John Mattera, two world-class scuba divers, who teach themselves to think and act as pirates while searching for what would be only the second pirate ship ever found and positively identified.
Pirate ships were built for stealth and invisibility. They filed no manifests with any agency or government. When they went missing or sunk, nobody went looking for them. They simply disappeared into the ether.
I was pleasantly surprised to find out that pirates did wear eye patches and have peg legs and have brightly colored beads. I never knew what the beads were for. They really were for frightening and terrifying their prey.
Piracy was risky business, and injuries were commonplace; a single lost limb or gouged-out eye could end a pirate's career. To encourage pirates not to hesitate in battle - and out of a sense of fairness - many pirate crews compensated wounded crewmen in predetermined amounts.
