Built to take your instrument
The payload bay is designed for integration work, so a sensor your team already trusts can go to sea rather than being replaced.
Reconfigurable catamaran platform for custom sonar, sampling and sensor payloads.

ModCat is the platform for teams who already know what they want to measure. Rather than fixing one payload into one hull, it treats the catamaran as a carrier: a stable, reconfigurable deck that accepts sonar, sampling gear and third-party sensors. It is the vessel we most often build on for research groups and institutional labs with instruments of their own.
Detailed specifications are issued per configuration — payload selection drives most of the numbers that matter.
| Platform | Modular catamaran |
|---|---|
| Deck | Reconfigurable payload bay |
| Payloads | Sonar, sampling, third-party sensors |
| Mast | Camera and antenna mounting |
| Control | Remotely operated |
| Typical use | Research, survey, custom missions |
Configurations vary by payload, water body and survey requirement. Tell us your site and we will send the specification that actually applies to it.
The payload bay is designed for integration work, so a sensor your team already trusts can go to sea rather than being replaced.
Reconfiguring between survey, sampling and inspection roles avoids buying and maintaining a separate vessel for each.
Twin hulls give the steady, predictable attitude that sensitive instruments need to produce data worth processing.
We do the mechanical, power and data integration ourselves, so the payload arrives working rather than merely mounted.
