The engine roars to life, launching me out of a deep slumber and into reality. “That’s not good,” I think out loud. Rocking in my bunk inside the sailboat, I realize the wind is still driving us against the ocean swell. We do not need to be using the engine right now, so why is it on? Bracing myself, I climb into the cockpit as Paul, the captain, swings us over hard to starboard while staring wide-eyed ahead into the darkness. We are on a collision course with an Indonesian fishing boat shrouded in darkness, and it’s close enough to violate the ceiling of a safety stop. Rubbing the sleep out of my eyes, I count a handful of men staring back at us as they also take evasive action. One of them is standing at the railing brushing his teeth while we run parallel alongside one another for a moment.
Luckily for us we didn’t collide. I went back to sleep with another adventure to share. If you were to meet me today, working a full-time job in Canada alongside Lake Ontario as it freezes, it would not be obvious I spent two of the past four years traveling. Balancing a life of adventure with one of responsibility, I feel fortunate to have explored some very remote places in our world–both above and below the water. But before I was able to explore the Pacific Ocean, I first had to navigate a personal path of conflicting identities in order to find the confidence to jump into the unknown.
For my entire life, I have been more comfortable in the water than on land. My childhood memories consist of watching my parents dive under the water for hours at a time and swim in the currents of the Thousand Islands in the Great Lakes region of North America. I followed the predictable path of our society. I worked hard, achieved an engineering degree, and secured a job. Fortunately, I was able to continue exploring the outdoors with this busy life. Long weekends were spent diving in the Great Lakes or camping in the back-country. I was comfortable enough; however, there was no real satisfaction in my life. As the years ticked by, the gap between my reality and dream world grew. Something had to change, but I did not know where to find the catalyst.
Like any other armchair traveler, I idolized the explorers from the Age of Discovery. Adventure books weighed down my bookshelf while travel documentaries glowed on the TV screen in my room at night. I understood what made me happy, but I was unsure of what I stood for and believed in. I was living a life in conflict with the trajectory I wanted to be on, but I had no idea of how to become an ‘explorer’ who lived a life in pursuit of the unknown. While commuting to work each day in a crowded subway, I daydreamed of sailing the oceans and exploring the underwater world. As I grew increasingly more frustrated, one day I unloaded my concerns on a friend. They had the nerve to say I was ‘living in a dream world’ and needed to focus more on my real life. This hurt to hear at first, but then it dawned on me! If dreaming was a part of my life, then why couldn’t I make it a reality, too? This was the catalyst I needed.
I finally understood that even though others might see my dreams as frivolous, it was okay for me to follow a path that was meaningful for me. Like a weight lifted from my shoulders, I discovered it was okay to be uncomfortable with the status quo. With this in mind, I quit my job, packed a bag, and with no concrete plans, bought a one-way ticket to go halfway around the world.
One-Way Ticket To Ride
I found myself flying to the Marshall Islands with a one-way ticket to meet someone I had only communicated with over email. The customs officer did not find it amusing, but after some tactful negotiation, I was let into the country and even offered a free ride to the marina. It was 2016, and I was on my way to meet Tom, the captain of a 53-foot, steel-hull ketch named Karaka. Tom invited me to join his crew and help them sail across the Pacific. Even though blue-water sailing was new to me, for him it was a lifestyle. He was nearing the end of a 12-year circumnavigation after saving Karaka from a scrapyard in Hong Kong. Along the way, he would have crew join him as a co-operative, which is how I ended up spending eight months on his boat exploring the Marshall Islands, Micronesia, and Papua New Guinea.
When not visiting uninhabited atolls, the outer communities we visited were so isolated that we were asked to help out by delivering fuel, cooking oil, and mail. During this trip, our daily routine consisted of free diving on pristine coral reefs, gathering coconuts, and sharing meals with some of the friendliest people in the world. From spearfishing with the local fishermen, exploring the shipwrecks and ruins of World War II, and partaking in long walks on the beach or up a volcano, it was a new adventure every day. As a shipwreck enthusiast, I am incredibly grateful to have had an opportunity to free dive to within sight of the HIJMS Nagato in the lagoon of Bikini Atoll and to dive on Japanese Zeros in waters of Rabaul. Never in my wildest dreams would I have imagined myself exploring these regions of the world; reality had transcended my childhood fantasies.
Just like diving is for many of us, once I started traveling, the passion grew and is now a core part of my identity. Flash-forward to earlier this year, and I am back in the capital of Papua New Guinea helping Paul and his partner repair their 34-foot sloop named Amanda-Trabanthea for a journey out of the country and into Indonesia. Adventurers themselves, they had just returned to their boat after sailing through the Northwest Passage. Over three months we managed to visit some of the most hospitable and isolated regions of Papua New Guinea and Eastern Indonesia. I was lucky enough to go diving in Port Moresby, the Banda Islands, Wakatobi, Komodo, Lombok, and Bali. By the time we survived the near-collision with a fishing boat, I had come to expect the unexpected and cherish the exciting moments in life.
Explore The Unknown
Diving and sailing share a lot of similarities. Both are perfect for getting off the well-beaten track to explore places of our world few have ever seen. We must be confident in our abilities and have the appropriate training to safely handle the unexpected. A strong technical understanding of the physics and equipment required to operate safely is very important. Meticulous planning is essential for completing long passages and technical dives. But most importantly, it is the adventure from exploring new places that makes it so fun and gives us reasons to continue doing this. I strongly believe that communities such as GUE play a pivotal role in society by encouraging and promoting exploration within the individual. With time, I will combine my passion for both diving and sailing to help discover some of the most remote and beautiful corners of our world. If you have never sailed before, I highly recommend it.
I am back in Toronto where this journey began. I’m working full-time; however, this time with a much more solid understanding of myself and as well as a greater appreciation of the world we share. Only by stepping outside of my comfort zone to explore our world I was able to overcome the uncertainty that kept me from living an authentic life. Author Dale Dauten put it succinctly, “Success is an act of exploration. That means the first thing you have to find is the unknown. Learning is searching; anything else is just waiting.’’
During my travels, I realized that we cannot let others define us. We must reach beyond personal boundaries, take a risk, and venture into the unknown. In doing so, we become explorers in our own reality, which is the only reality that matters. So, rather than daydream about future adventures, we need to believe we can incorporate those dreams into our lives. All we have to do is to dare to take that first step into the unknown.

Undergoing PFO Surgery as a Team: Deana & Bert’s Excellent Adventure
People like to give GUE a hard time for their uncompromising focus on team diving. But a pair of divers from GUE Seattle has taken it to a new level: getting their PFOs fixed together. The team that bends together, mends together? Instructor and tech diver James D. Fraser willingly tells the tale.

This is the follow-up to the story that ran in InDepth December, 2019: No Fault DCI? The Story of My Wife’s PFO
It has been a year since my wife Deana had a decompression illness (DCI) hit in Bonaire requiring her to do a Table 5 recompression profile in a hyperbaric chamber. At the time of my previous article’s publication, Deana had a Transthoracic Echocardiogram (TTE) bubble study and found out she did have a small to moderate patent foramen ovale (PFO). Two physicians offered similar options for Deana to consider when it came to her diving activities:
- Stop diving, as this eliminates any risk of DCI in the future.
- Modify her dive profiles to be more conservative: diving only once per day, diving nitrox 32 using air tables, and/or extending her decompression profiles and safety stops.
- Have the PFO repaired, knowing it is not a guarantee, and continue diving as conservatively as possible.
Deana had initially decided to wait on doing a PFO closure until after our daughter’s wedding in March 2020, but she realized very quickly that being “conservative” was not in her nature. Deana had already returned to diving within 12 days of her hyperbaric chamber ride. In the 46 days since her treatment, Deana had already done another 15 dives to depths of 90 feet; being conservative really was proving to not be an option for her. Diving was just too much a part of her life.
In mid-November, Deana reached out to cardiologist and tech diving instructor Dr. Doug Ebersole for a second opinion on the bubble study and his advice about her options. Dr. Ebersole gave Deana the same response as the other physicians; but, knowing Deana and her passion for diving, he suggested that she have her PFO fixed, since her plan was to continue diving.
Deana also spent time talking to other divers who had been diagnosed with PFOs—some who had them repaired and some who had decided against it—in order to get a more complete picture from both a patient and a doctor point of view. One of the final conversations that pushed Deana to have her PFO repaired was with a coworker who was a nurse practitioner in cardiology with knowledge of PFOs and diving. Her coworker was pretty blunt, stating, “Why are you playing Russian Roulette? You have worked in cardiac and know the risks.”
Some of these risks include Arterial Gas Embolism (AGE), Venous Gas Embolism (VGE), and cerebral embolism. That was the final “Aha” moment to tip the scale and get Deana to schedule her PFO repair, since “Russian Roulette” was exactly what Deana was doing based on her diving activities following her DCI hit.
Team Approach to Treatment
Bert Berzicha, one of our GUE Seattle community members, also completed his TTE as a result of having had some symptoms of DCI in the past. The test confirmed the presence of a large PFO. Deana and Bert compared notes initially and discussed diving as a team on future dives using more conservative decompression profiles than other teams, allowing the other teams to get out of the water sooner. Deana, however, related what she had learned from talking with her coworker and changed her mind about diving conservatively and instead decided to get the PFO repaired.
Deana did not want to take the risk of neurological deficits that could be irreversible. Deana suggested to Bert that he come with her to have his PFO repaired at the same time. Bert continued to research the subject, looked at his work schedule, and decided doing a “team” procedure made sense. Just as a dive team shares a plan, resources, and emergency procedures, a medical procedure shares similar benefits when working as a team.
It was time to plan a date for both of them to have the procedure. Deana and Bert both live in the Seattle area. Dr. Ebersole lives in Lakeland, Florida, so logistics included time off work, pre- and post-surgical care, flights, hotels, and transportation. Deana arranged to have her sister Jessica fly into Tampa from Dallas, prior to them arriving, so she could pick them up from the airport to make it to the hospital in time for the procedure. I was going to be in Australia on a business trip at the time, so I was not able to be there pre-surgery. I ended up reworking my return trip and flew from Canberra, AU to San Francisco, then on to Tampa, to land just an hour after their surgeries were finished and meet them back at the hotel.
Even though Deana and Bert could fly home 24 hours after the procedure, they decided to stay the weekend just in case there were any complications and to take it easy. Deana, however, had a different take on “easy.” The morning after surgery, Deana was invited by Dr. Ebersole to watch a procedure that he and his team perform called the “WATCHMAN” procedure (less than 24 hours after post-op). Then we picked up Bert and Jessica, and jumped into the truck to do a 300-mile, five-hour road trip to High Springs, FL, to take a tour of the Halcyon facility and say “Hi” to Orie Braun, Lauren Fanning, and Mark Messersmith; stop in at Global Underwater Explorers (GUE) HQ to buy some swag; and drive down to Ginnie Springs to see where Cave 1 may take place in Deana’s and my near future. Not bad a day after surgery.
It was at Ginnie Springs where Bert came to Deana and stated he thought he had active bleeding. We all paused and turned pale, knowing we were not in a great location for this to be happening, but after being assessed by Deana it turned out to be post-op bruising from the surgery. This did, however, make us stop and think, “We just drove 300 miles away from the hospital we had decided to be close to in case of complications.” I am sure Gareth Lock would find a really good human factors story in there somewhere.
Deana’s PFO adventure Timeline
- OCT 8: 47 m/153 ft technical dive resulting in a DCI episode requiring recompression.
- OCT 20: First dive post-chamber ride to 16 m/52 ft
- OCT 29: TTE Bubble Study; “Deana has a small to moderate PFO”
- NOV 17: Dr. Ebersole receives Deana’s TTE study for a second opinion
- NOV 21: Deanna dives now to 28 m/90 ft
- DEC 4: Last dive before PFO repair. In the 46 days since her hyperbaric treatment Deana made 15 dives: “Conservative Not”
- DEC 12: Deana and Bert have PFO procedure
- DEC 13: Lakeland to High Springs road trip
- JAN 27: First dive post closure—15 m/49 ft and spaced dives 2-3 days apart
- FEB 15: Started doing multiple dives daily no greater 15 m/50 ft
- MAR 8: PFO follow-up; OFFICIALLY cleared by Dr Ebersole to dive
- MAY 7: Dives now pushing 30 m/100 ft
- MAY 31: First Tec dive to 33 m/110 ft
Since May, Deana has done 120 dives in 2020 with a max depth of 52 m/170ft, which she did on September 12. Deana has gone back to no-restriction diving and has completed 16 technical dives since this summer. Some of these have been assisting with photogrammetry dives.
- 46 m/150 ft to 52 m/170 ft: 3 dives
- 40 m/130 ft to 46 m/150 ft: 5 dives
- 30 m/100 ft to 40 m/130 ft: 8 dives
Getting Personal With PFOs
COVID-19 has prevented us from doing a dive trip this year, which is the one main test we still have yet to do: repeat the scenario that always led to her getting DCI, which was three consecutive days of recreation and tech dives, to see if she experiences any recurrence of DCI symptoms. 2021 will hopefully open up this opportunity, or by that time Deana will already be training for GUE’s Tech 2 course. In either case, Deana and Bert are both very happy to have had their PFOs repaired; both have seen improvements in their health in other areas such as endurance, no longer being easily winded, and, in Bert’s case, less headaches, which he had prior to the PFO closure.
To get a PFO repaired is a personal choice, and no one should ever take surgery lightly as it has its own risks. Divers with PFOs need to do their own research and consult an interventional cardiologist, such as Dr. Ebersole, who understands diving. Only then can they make an informed choice based on their own unique situation whether or not a PFO closure is right for them. This article is meant to show the process and outcome of two very experienced and ambitious divers who made the choice to have their PFO repaired and the results of that decision.
