News: A New Chapter for Open Ocean
After 20 wonderful years, Terry and Ariel are retiring. We are excited to carry on their legacy of excellent service and reliable products under new ownership. Thank you for your continued support! |
The Quencher System
The Quencher bridges the gap between complex automation and manual reliability. We’ve moved the controls out of the bilge and into your cabin, giving you a professional interface without the "mystery cycles" of fully automated systems.

- Remote Control: A compact panel allows you to operate the system from a convenient location in your cabin.
- Total Transparency: Hands-on controls mean you always know exactly what your system is doing.
- Two Configurations: Choose between a Manual panel for service areas or a Manual/Electric panel for the cabin.
