HR Wallingford Ltd ARCboat Lite

The ARCboat Lite has evolved from our award-winning ARCboat. This new, smaller lighter solution shares many of the features of the original vessel, but we have optimised it to carry out bathymetric and river current surveys in lower flow environments. With a robust, lightweight hull, the ARCboat Lite has been specifically designed for use by a single person. The ARCboat Lite is a highly effective alternative to larger, more expensive survey vessels.

The ARCboat Lite’s strengthened fibreglass hull was designed by naval architects to minimise air entrainment and deliver consistent, high quality data collection. The ARCboat Lite shares many features with the original ARCboat, from the bright yellow-green hull that makes it easy to spot on the water, to the detachable bow for easy transport. The lighter weight of the ARCboat Lite, however, has allowed us to fit a quick release catch, and a self-guiding and draining slot so even with cold, wet hands the bow is easy to attach. It also has the same moon-pool dimensions so no need to buy new adpaters - equipment is interchangeable between the ARCboat and ARCboat Lite.

The ARCboat Lite’s thrusters are battery‑powered so the vessel produces no emissions and is extremely quiet during operation. The fixed external thrusters with aft mounted rudders make it highly manoeuvrable. Using differential thrust delivered by electric motors, it can turn in its own length. The rudders allow smooth ferry gliding with precise levels of control. The externally mounted thrusters are easy to maintain or replace, and eliminating the propeller tubes means that the hull can be completely sealed. The ARCboat Lite will be available with two thrusters designed for slower flow environments of up to 2 m/s, or with four thrusters optimised for faster flows of up to 3 m/s.

ARCboat Lite is supplied with a remote control with a range of up to 2 km, and displays the on-board battery voltage.
