treated by the Tidal Wave type II sanitation system and pumped out or released outside of the sanctuary. R/V Manta is powered by twin Caterpillar C32 ACERT engines, each delivering 1600 bhp at 2300 rpm. The propulsion package includes ZF 3050 transmissions which drive Hamilton Jet HM 571 water jets. The vessel cruises at 27 knots and can reach speeds topping 34 knots. The Manta's fuel consumption is excellent, using approximately five gallons per nautical mile at speeds ranging from 22 knots to 31 knots fully laden. A range of 650 nautical miles is possible with the 3600 gallon fuel capacity inclusive of reserves. Similar to the other NOAA catamarans built by All American Marine, the Manta uses hydrofoil technology and the Teknicraft
Design signature hull shape. The semi-displacement catamaran hull shape developed by Teknicraft Design of Auckland, New Zealand provides a smooth ride while producing extremely low wake wash energy.
