FOUNDERS

Founded by Florida natives with decades of combined marine experience, Frequensea Marine was built

on technical expertise, craftsmanship, and

a commitment to precision.

 

Mike, a seasoned captain with an in-depth understanding of vessel operations and marine electrical systems, partners with Curtis, a low-voltage specialist with more than 25 years of hands-on integration experience. Together, they bring a rare combination of real-world boating knowledge and advanced technical capability to every project.

 

Frequensea began with a focus on custom marine audio refits, perfecting sound on the water through meticulous installation and clean system design. As demand grew, so did our capabilities. Today, we engineer fully integrated marine electronics solutions — from advanced navigation systems and helm upgrades to Starlink connectivity and complete vessel refits.

 

Our approach is rooted in thoughtful system design, seamless integration, and long-term reliability. We don’t just install equipment — we design solutions that enhance performance, safety, and onboard experience.

 

With strong partnerships across leading marine technology brands and a reputation for solving complex onboard challenges, Frequensea Marine has become

a trusted name throughout Southwest Florida.

 

Engineered with precision.

Installed with purpose.

Built to perform.
