- Designed by French naval architect Pantocarene.
- Planing hull constructed for strength and lightness.
- Innovative beak bow design to steady pitching and allows high speeds in bad weather.
- Specially developed skeg aft enhances directional stability and a separate wheelhouse construction on resilient mountings minimises noise and vibration.
- Hull design makes significant reductions in fuel consumption.
- The first two ORC 171 pilot vessels are working alongside more traditionally designed vessels and are showing a fuel saving of around £80,000 per year, per boat.
