Volvo Penta has brought its IPS propulsion system to the larger semi-displacement yachting segment with the updated D13 IPS 1350 semi-displacement (SD).
The new system’s torque curve has been modified to cope with higher thrust loads at slower speeds and also has a wider speed range down to 19 knots (formerly 25 knots).
“Recently, we have seen a trend of larger yachts going down in speed,” explained Björn Rönnvall, product manager at Volvo Penta. “We wanted to be able to bring the benefits of our IPS system to these larger, slower semi-displacement yachts and that is what we have achieved with this update.”
The key advantages of the Volvo Penta IPS, compared to inboard shaft installations, are increased onboard comfort, fuel efficiency and a longer range. The individually steerable IPS drives – controlled by the joystick – make for responsive handling and pilot-like control when manoeuvring and docking. This allows owners to navigate in tight spaces, perform tricky manoeuvres and maintain stability in all sea conditions.
With this new edition comes the introduction of two new propellers to the Q-series – the QS4 and QS5 – both for use with the new D13 IPS 1350 SD only.
The new D13 IPS 1350 SD edition is already in use in the larger yachting segment – the Absolute Navetta 73, ISA 93 Extra and the Arcadia Sherpa XL are all powered by the new edition as well as the new Mangusta 33.
