CHCNAV Apache 6 USV
CHCNAV Apache 6 – multibeam and LiDAR survey boat for demanding water
The Apache 6 is an integrated platform for 3D bathymetry, underwater object positioning, offshore construction, archaeology and wreck search.
Its detachable triple hull is optimized for Norbit multibeam sonars, and CHCNAV’s absolute straight-line technology keeps it on line even in strong currents.
Stable, agile and ready for multibeam
A carbon-fibre, three-part detachable hull is easy to transport and stable in near-shore conditions. Titanium rotating thrusters turn in 2 m for narrow waterways, and an integrated SVP launcher completes multibeam surveys in one deployment. Optional iLiDAR maps above the water at the same time. See how single-beam, multibeam and ADCP surveys work in our 3D animations.
Why choose the Apache 6
Multifunctional platform
Multibeam and LiDAR for complete 3D data.
Stable triple hull
Detachable floats for fast currents.
Automated SVP
Sound-velocity profiles without stopping the job.
Rotating thrusters
2 m turning radius for narrow waterways.
Smart remote
Android controller with 4G and radio links.
Carbon fibre
Light, strong, easy to handle.
Multibeam and LiDAR in one mission
Fit optional multibeam echosounders and a LiDAR scanner to capture high-resolution data below and above the waterline for object location and offshore construction.
Steady in fast currents
The tri-hull design and detachable side floats keep the boat stable and adaptable – rated for wind level 6 and wave level 4.
Complete multibeam solution
The optional automatic sound-velocity profiler is controlled from the remote and installs or removes in under a minute.
2-metre turning radius
Intelligent rotating propellers redirect the water flow for a 2 m turning radius in narrow waterways, and support both differential and servo steering for efficient multibeam lines.

Apache 6 FAQ
Which multibeam does the Apache 6 use?
It is optimized for the Norbit multibeam series, and also carries other sonars, 3D laser scanners, side-scan and water-quality sensors.
How does it handle currents?
The triple hull with floats and CHCNAV absolute straight-line control keep it on line in strong currents.
Can it measure sound velocity automatically?
Yes – with the optional automatic SVP launcher, controlled from the remote.
