About Marriner Marine Technologies
Founded to bring modern technology to real-world marine safety, starting with the people who work on commercial fishing vessels.
Where it started
Marriner Marine Technologies began with a personal connection to the commercial fishing community and a practical concern for the people who work in demanding marine environments. The original project explored technology that could support man-overboard detection aboard vessels.
As the work developed, it grew into a broader vision for marine safety and crew-awareness technologies. The company is in an early research and prototype phase, focused on careful testing and responsible refinement.
Why it exists
We believe modern technology can give crews better awareness during time-sensitive emergencies. Our first effort focuses on man-overboard detection, with a longer-term goal of supporting broader search-and-rescue and vessel-safety applications.
The name behind the company
The Marriner name honors the founder's grandfather, whose last name was Marriner and who was well known within the local commercial fishing community.
It reflects both the company's family roots and its commitment to the people who work and travel on the water.
Founder
Jacob Radzieta is the founder of Marriner Marine Technologies. Drawing on his engineering background and connection to Cape May County's marine community, he is leading the independent development of the company's first system, MMT Sentinel.
Mission
To develop practical marine safety technologies that improve awareness and support faster, more informed emergency response.
Vision
A marine industry where modern technology better protects people across commercial, recreational, and large-vessel operations.
Values
Safety, reliability, practical engineering, respect for working mariners, responsible innovation, honest testing, and continuous improvement.
Long-term goals
Continue validating MMT Sentinel through expanded vessel trials, prepare it for vessel-scale deployment, develop commercial hardware, expand into recreational and large-vessel applications, and build technologies that help locate and recover people after marine incidents.
How we work
Design around real vessel conditions, test before making claims, document engineering decisions, listen to vessel operators, protect confidential information, and favor dependable operation over complexity.
Let's talk
We welcome conversations with vessel operators, marine-safety professionals, and potential partners.
