ARCboat is our award-winning state-of-the-art remote controlled survey vessel. Over 180 vessels are operating worldwide, on all six continents, in environments from mountain rapids and wide estuaries to industrial ponds and reservoirs.

Conducting hydrometric and bathymetric surveys worldwide

ARCboat can carry a variety of Acoustic Doppler Current Profilers (ADCP) and other instruments to collect river and estuarine data including flow, depth and suspended sediment concentrations.  

In the UK, the Environment Agency uses ARCboats for routine hydrometric and bathymetric surveys. 

ARCboats are safer than manned vessels as operators can survey from the bank rather than venturing out on to the water. They also minimise disruption to the environment, as they are operated by extremely quiet, zero emission electric motors. 

Working closely with users we have perfected ARCboat to meet their exact needs. As user's needs evolve, so has the ARCboat, resulting in the brand new ARCboat Lite.

ARCboat Lite

ARCboat Lite is a more compact version optimised to carry out bathymetric and river current surveys in lower flow environments. This smaller vessel weighs just 15 kg and 1.3 m long, with a detachable bow, so fits inside a hatchback.

High manoeuvrability and shallow draft combine to allow the ARCboat Lite to reach more of a survey site than has been previously possible. Lite is easily deployed by a single person and operates in flows of up to 1.5 m/s, in water as shallow as 22 cm. 

The price of ARCboat Lite is less than the larger ARCboat.
