High-Speed Riverboat Tethered Boat For Fast Flowing Waters For Extreme Measurements For the best data quality in the most challenging measurement conditions, the Oceanscience High-Speed Riverboat (HSRB) is the new benchmark for acoustic doppler current profiling for discharge measurements. The advanced hull design allows the boat to slice through standing waves and still maintain instrument position and data collection. Fast flowing water, often problematic with conventional tethered boat designs, can be handled with relative ease with the High-Speed Riverboat. Handle High Water Velocities With New Hull Design The Oceanscience High-Speed Riverboat has gathered data at water velocities over 20fps (6m/s). The state-of-the-art trimaran hull design cuts through surface waves, strongly resists overturning, and maintains instrument orientation in high flows. Any instrument up to 8” in diameter may be accommodated, with mounting options for commonly used profilers available. For sites where tethered boat measurements have been impossible, or data were too poor to be of value, the High-Speed Riverboat is the solution. Standard Configuration Made of high impact UV resistant ABS, the HSRB is strong and robust to cope with the worst deployment conditions. The standard boat configuration includes foldable kick-up fins, an 8 pin ADCP connection, communications cabling for Oceanscience Hydrolink radios, a 12V battery with ADCP on/off toggle switch and an external stub antenna. All boats carry a 1-year warranty on the hulls.
