CUSHENDALL, NORTHERN IRELAND
Leisure
Built by Redbay Boats in Cushendall, Northern Ireland, the Pladda Porpoise is a heavy-duty, high-performance vessel powered by twin Volvo Penta D11 engines paired with Q-SPD QSD220 surface drives.
Engineered for exceptional efficiency across a wide operational window, from cruising to flat-out sprints - this setup pushes the 22-tonne vessel to impressive top speeds of 41 knots.
With strict noise limits increasingly enforced in harbors and waterways worldwide, acoustic discretion matters more than ever. Thanks to advanced propeller hydrodynamics and a noise-muffling composite housing that dampens exhaust notes, Q-SPD drives deliver exceptionally quiet operation.
During close-range pass-by testing (measured at full speed from just 25 meters away), the Pladda Porpoise recorded an astonishing 67 dB while running at 40 knots - proving that high-speed propulsion doesn’t have to come at the cost of high noise levels.
