Aqua Cat’s engines purr a low hum as she glides on blue-glass crystal seas casting a dark shadow on the white powder sugar sea floor. A squadron of flying fish flutter their skimming escort across low wave tops at our bow. The golden sun simmers the water in comforting warmth. Besides the gentle chortle of our engines at low throttle, there is a blissful, structural silence here in the eastern Caribbean.

We have left the earth as we know it, transcending turmoil and scarcity and fear. We skim across open ocean to a new world, a world so fantastic and exotic and improbable it can only be described with fictional analogies. Nothing on this earth is- in fact- this remarkable.

Fiction is full of this: The Wizard of Oz, Alice in Wonderland, Harry Potter, Star Wars. These made-up tales of unlikely journeys to unreal places with fantastic creatures. But this journey is real, and our gravity-enslaved earth is only separated by the thin surface tension of the sea to a place where we float and fly and glide like superheroes, where frightening beasts displace us down the food chain but become our companions, guides and guardians.

And amongst their opulent welcoming embrace, the sea and its beasts convey quiet worry.

We are tourists. I make no apology for that. We are aboard the dive ship “Aqua Cat”. She is a three-level, 102-foot live-aboard with a luxurious 35-foot wide beam. She draws only about 6 feet of water. As a broad, stable catamaran, she is fast, quiet and maneuverable. She transits rolling seas in comfort. Aqua Cat sails from Nassau, Bahamas east across an open Atlantic strait to the Exuma island chain. It’s about 100 miles of open ocean.

Three weeks ago, I knew little about the Exumas. Few people do, mostly only SCUBA divers, billionaires and cocaine traffickers. Lying as the first real landfall of substance along the latitude between the African Western Sahara and the Americas, the Exumas are the natural reef fence that separate the inner Caribbean with the vast ocean wilderness and abysmal plains of the deep Atlantic. Beyond the Exumas, there lies only the bottomless wild sea.

For the 32 divers aboard Aqua Cat, the gate to the wild, open sea and the deep Atlantic has been left open. We gaze beyond it and even swim through it.

Now I hover in silence 60 feet below the surface gazing into the true abyss, the blue-black transition to the open Atlantic. This is where the continental shelf plummets to depths measured not in feet or fathoms, but miles. I watch in silence, waiting. Perhaps something will emerge from down there. Something really big.

Michele, call her “Shell”, is our divemaster. When we reach the abrupt cliff at about 40-feet of depth plunging into the abysmal plain of the continental shelf, Shell gestures with both arms like an underwater ballerina taking a bow in front of the vast submarine theater. As Shell is a prima ballerina of the undersea world, her gesture seems appropriate. This is it, she indicates, the end of the continent. Shell is one of our instructors back in the U.S. where we got our NITROX diving certification. Shell’s goal on this trip is to complete every dive, five dives each day including a night dive. It’s a tough schedule with about 4 hours plus of underwater time per day. She has inherited us as human pilot fish during our dives. While I gawk around looking for creatures and adjusting my camera, she makes sure I don’t wander off underwater, run out of NITROX and forget to surface. It is so remarkable down here that’s not out of the question.

Terrestrial travel is encumbered by gravity and the hard platform of earth with its constant horizon. Not down here. Down here the rules are completely different. We don’t even breathe normal air. Each inhalation through my SCUBA regulator is enriched with more oxygen than we breathe in the atmosphere. The NITROX gas in my large capacity SCUBA tank allows me to stay down longer and recover faster on the surface so I can return to the edge of inner space more quickly. But should I descend too deeply or rise too quickly, that same benevolent gas mixture of oxygen and nitrogen could put me in a dangerous corner of the dive envelope. To avoid trouble floating in inner space I watch a bank of computers on my arm measure my depth, pressure, time and remaining NITROX gas. But it is hard to stay focused on the numbers down here. It is just too… fantastic. And this NITROX goes down pretty easy.

Our undersea party skirts the drop-off to the Atlantic abyss at the edge of the Caribbean in a “wall dive”. It’s a dive along the edge of a deep drop-off that forms this underwater cliff between the coastal shelf and the deep sea. Some of our divers descend deeply along the wall past 100 feet. At that depth color and light are filtered by the water overhead to merge into a blue-grey monotone less sensational in appearance to the human eye than the moderate depths I favor. My party is contented with the middle-depths of 30-80 feet. There is more life here, more color. And less danger.

Our schedule aboard Aqua Cat this week has been brisk. Wake, eat, dive, dive, eat, dive, dive, eat, dive. Five dives per day are available to divers on Aqua Cat, although few divers will do every dive, except, of course, Shell. There is too much else to do.

During breaks from diving we laze on the upper deck in Caribbean sun, watch the rocky islands slide by, stay on the lookout for passing whale pods (we spotted rare pilot whales during dinner) and take excursions to shore on one of our two dinghies.

The barren islands are worth exploring. The weather here in May is calm and warm. One island harbors a shallow saltwater marsh with crystal clear water, home to exotic great hammerhead sharks. We take the dinghy to shore amidst a covey of weathered, practical sailing yachts and a pair of mammoth, billionaire luxury superyachts crewed by polo-shirted Ken dolls scrambling around the decks in hurried chores.

It would appear someone lives here, at least part time. An island caretaker who watches over the yachts moored in the lagoon and makes sure that the same number of people who land on the island each day actually leave it. Beyond that there are only scrub plants, palms, an assortment of reptiles ranging to quite large iguana, sea birds and the fish, sea animals and crustaceans that occupy the littoral environment.

On one expedition from Aqua Cat to a remote deserted island my girlfriend Jan Mack and I discover a hidden trail into a low mangrove thicket. A sign has fallen into the sand at the trail’s entrance. It offers only one word, “DANGER”. We follow the overgrown trail and discover it is, in fact, quite treacherous. Coral and rock outcroppings have been eroded to razor-sharp sinkholes easily large enough to swallow a person. Fetid pools draped by spider webs lurk at the bottom. The crusty terrain feels unstable under our amphibious sandals. After a half-mile push inland we retreat, satisfied that there is slim chance of finding anything remarkable in this low jungle mangrove. As it turns out, we are wrong. Four days later another person from Aqua Cat in the same region shoots a photo of a mammoth hammerhead cruising through the mangrove shallows. It would have been a spectacular sight.

Before we are barely able to savor our experience, Aqua Cat is crossing the open strait back to the Bahamas at the end of our expedition. There has been too much to digest, too much to take in, too much to experience. We’ve packed a month into a week aboard Aqua Cat. To try to take in the grandeur of the sea in a one-week trip is an absurdity, like trying to get a satisfying drink from a gushing firehose. There is simply too much to contemplate, too much to absorb, to many sensations to manifest.

But as remote and pristine as the Exumas felt we heard a quiet cry from her waters and her beasts. They are threatened, retreating, shrinking, dying. On the remote beach we found, Jan Mack and I spent the first thirty minutes picking up plastic waste and trash from a passing yacht crew who had made a bonfire on the empty beach and left their offal behind. In these waters plastics are dangerous to turtles, rays and sharks. They take years to decay, if at all, and can trap marine animals and strangle them or choke their digestive tracts. Some of the big sharks who guarded each of our dives showed signs of fin damage from boat propellers or had fishing hooks lodged in their mouths. On one dive, I swam after a cloud of drifting plastic bags to retrieve them before they drifted into the deep where they may wind up in a whale’s stomach.

I knew we would see the impact of man even in the remote Exumas. Part of the reason we wanted to be here was a looming sense that the clock ticking toward environmental calamity has passed the point of no return. That we are losing the Exumas and all places like her at an irreversible pace. I hope that is not true, and I’ve made an internal effort to manage my life at home in Michigan so I use less plastic, recycle more trash, drink from reusable water bottles and give to the organizations that protect the sea and her creatures.

Sailing on the Aqua Cat gave us a look into the wild sea and her massive expanse, exotic wilderness and remaining pristine beauty in a way no other experience could. That is priceless and ephemeral. It is something to be treasured and protected for as long as we can.
