Women Divers: Part of the Navy Team

Tradition and equipment discouraged women from becoming divers. Navy divers were exclusively male for over one hundred years. Dive gear, designed to fit men, was heavy and oversized for female divers. Hull Technician Donna Tobias made history in 1975 when she graduated from the Navy’s Deep Sea Diving School as the Navy’s first female hard hat diver. “She had to prove herself, to be twice as good at everything, and she was,” remembered retired Master Diver Steven Lechner.

This exhibit examines the challenges and achievements of some of the first women Navy divers. Through determination, persistence, and a love of diving, these early pioneers proved themselves in a male-dominated world to become valued, respected members of the Navy diving community.


Use the tabs below to explore their experiences in their own words.

“Babe, what do you want to be a diver for?”

Women became Navy divers for many reasons. Some had loved the water as children. TV shows such as Sea Hunt captured the interest of others. Some women, after they joined the Navy, became fascinated with the work the divers did. And some wanted a career where the standards for women were the same as those for men.


Mary BonninMary Bonnin became interested in diving when working at the Norfolk Naval Shipyard. A dive school slot became available to her unit when a male sailor decided not to go. A Chief Warrant Officer told Mary, “You couldn’t do it. Babe, what do you want to be a diver for? You’ll be thrown out of that school in a week.” His challenge made her determined to succeed.






Debra Bodenstedt“When I first came into the program there weren’t many sea billets available to women and this was one way to get to go to sea.”

Debra Bodenstedt







Linda Hubbell“It was like being a visitor in another world. I loved working in the water. I love the oceans, the marine life, the entire experience…still to this day.”

Linda Hubbell







Marie Knafelc“Every summer, come Memorial Day, no matter how cold and bleak it was in western Pennsylvania, my mother would take us children to the …swimming pool…Then came the TV show Sea Hunt…and the seeds were sown.”

Marie Knafelc 






Bette Bolivar Bush“When I was 8 years old, I was a near-drowning victim and had to be resuscitated. From then on, I told myself I would conquer both the seas and my fear of the seas by learning more and becoming part of the underwater environment. I took swimming lessons and gradually eased my way back into the water…and eventually earned a degree in oceanography.”

Bette Bolivar Bush





Karin Lynn“A friend wanted to take lessons and needed a buddy, so I went through the dive lessons with him and got qualified and then found out I really enjoyed it.”

Karin Lynn







Karen Kohanowich“What really got me into diving was that the standards for women were the same [as for men]. Women had to do the same number of sit-ups and push-ups. They had to climb up and down the dive ladders wearing the same 200-pound Mark V dive system.”

Karen Kohanowich

Anatomy is Not Destiny

Diving officials often cited the physical differences between men and women to discourage women from becoming divers. Less upper body strength, less aerobic capacity, higher risk of the bends, hormonal differences, and pregnancy were used as reasons for them not to dive.

Medical science has disproved these ideas about women’s physiological fitness for diving. Today the primary restriction to diving is pregnancy. The physical qualification for women divers is the same as those for men: be physically fit and in good health.


Donna TobiasDonna Tobias became the first woman to graduate from the Navy’s Deep Sea Diving School in 1975. She had to handle some 200 pounds of gear, including a Mark V dive helmet, weighted boots, and a heavy canvas suit. She dove in water that was often dark, cold, and turbulent, accompanied by men, some of whom were supportive and many more who resented her invasion of their domain.





Sue Trukken“…since I was small, nothing fit well. The dive dresses were too big, the boots were too big, and the breastplate stuck over my shoulders by several inches. I sewed towels into my shirts, making me look like a football player. This allowed the breastplate to sit higher, giving me some room to move my arms up. I wore my shoes covered by a pair of socks inside the boots so that the boots would not fall off of my feet. My tenders had to put three leather belts on my arms so that when the suit pressurized, the gloves would not blow off of my hands (it didn’t work).”

Sue Trukken



Marie Knafelc“Showing up at the Navy dive school as a 5 foot 4 inch, 120-pound woman, I was met with some skepticism. Though a few men had a problem of a woman in a ‘man’s profession’, the critical fact was I was small and the Mark V diving rig I had to dive and climb out of the water in weighed close to 250 pounds in the dry.”

Marie Knafelc

Challenge and Determination

In the face of physical hardship and institutional barriers, the first women Navy divers were determined. They struggled with equipment sized for larger bodies and an organization that was not always welcoming.


Donna Tobias

If you ever uttered the words, ‘I quit,’ you could never take them back, and there were plenty of eyes waiting to see me fail. I didn’t want them asking less of women, for anything.”

Donna Tobias







Linda Hubbell“Being a female Navy diver has to do with perseverance. You get tired of being told you can’t go on some job because you might get hurt.”

Linda Hubbell








Karen Kohanowich“You need to be strong. You need to be dedicated. You need to practice. You need to be serious about it.”

Karen Kohanowich









Mary Bonnin“It’s a matter of determination rather than skills. It helps to have someone behind you telling you that you can’t do it. To work in a man’s world you have to have an awful, awful lot of patience.”

Mary Bonnin







Kati Garner“I was getting so tired, I think I was in bed about 7 o’clock every night. But I knew I was going to finish [Navy scuba school] because I couldn’t see myself dropping out.”

Kati Garner







Sue Trukken“My diving class started out with 20 diving candidates of whom I was the only woman. By the end of the first two weeks we were down to thirteen. I survived this attrition by smiling the whole way through physical training and working myself to death.”

Sue Trukken







Linda Hubbell with dive school classmates“[My detailer] on the phone was offering me a job in Hawaii as an assistant biology technical officer. Only catch, I had to go to Navy diving school. Then he informed me there was one other bit of news that went with this diving school stuff. I would be the first female officer to ever go through. My Dad was a Navy Seabee qualified in underwater demolition, and I knew what Navy diving school meant. Gulp.”

Linda Hubbell





Rene Hernandez“…it’s very hard work… but it’s something that if you really want…in your life you just go for that. And so once you work that hard and you do it…you become…part of an elite group of people…”

René Hernandez







Marie Knafelc“Diving and submarine duty were part of the job that I had to do. To make a naval career in diving medicine, I had to become qualified in submarines. A dive school classmate found a submarine commanding officer willing to have a woman undersea medical officer to care for his crew. Because I was willing to go down in the bilges, through sonar domes, crawl up inside a missile and learn whatever the crew was willing to teach… [I] broke down any barriers the crew may have had when I initially appeared on deck.”

Marie Knafelc





A diver’s life depends on being part of a team. Divers train and dive in teams. Divers working in the water are supported by their shipmates on the surface. Teamwork is at the core of everything divers do.


Karin Lynn“…the diving community is also a very tight-knit, close group….the friends that I made at the Supervisor of Salvage and Diving…have been friends for life.”

Karin Lynn








Debra Bodenstedt“…women are part of the community within the Navy divers, and they are equally trained, equally capable, and equally successful as their male counterparts…you get out of it what you put into it.”

Debra Bodenstedt







Karen Kohanowich“…having separate standards is almost like sabotage. There’s no way you can have a good team. You know, what we’re here for is to do the work and be part of the team.”

Karen Kohanowich







“One of the other jobs that I’m probably most proud of was, while [I was] CO of this underwater ships husbandry unit, we removed 30-ton propellers from a carrier in the water…That is quite a task, an engineering feat, that’s done underwater.”

Debra Bodenstedt






Donna Tobias“And one of the things that exists…is the camaraderie. We all have each other’s lives in our hands. …But you’re all in it together…you get weary together, and you get cold together, and you laugh together.”

Donna Tobias







Marie Knafelc“When divers see a dive-pin on your chest, no matter who you are, they know you went through a rite of passage unique among divers. Everyone went through the same rigors of physical training. Navy diving is based up on a buddy system. Your life depends upon that buddy in the water with you. You have to trust them in their knowledge and ability, as well as they have to trust you to take care of them if things go sideways. The result is that the Navy diving community is another family within the Navy family.”
