Mackay Boats has launched the M10, a new 470 hull built specifically around mixed-crew racing and the increasingly technical role of body kinetics in the modern 470 game.
The timing is deliberate. Since the 470 became a mixed event, teams have been pairing sailors with different body mass, height, reach, and movement profiles. That changes how power is applied and how consistently crews can find the same rhythm, particularly downwind, where pumping, steering, and trim need to stay locked together.
The 470 is a measurement-controlled class rather than strict one-design, meaning hull shapes can vary within class tolerances. Mackay has used that space to rethink the platform from the water up. At 120 kg, the boat is light and highly responsive, and Mackay's pitch is straightforward: every movement counts, so the hull should convert physical effort directly into forward speed.
The most visible changes are at the bow and stern. The M10 carries increased volume at both ends to improve stability and balance under aggressive pumping, while the midsection retains the lines of Mackay's previous 470s to preserve familiar handling. Bow refinement was a priority, with a fairer, cleaner shape intended to cut through waves with less resistance when crews are pushing hard.
The deck is entirely new, the first full redesign from Mackay since 2001. The cockpit is wider, the gunwales are higher amidships for a drier ride, and the foredeck has been reshaped to reduce aerodynamic drag.
Maximum class-legal waterline length and deck width are both built in, consistent with Mackay's long-standing approach. On the M10, that maximum deck width extends further aft, giving the skipper greater leverage for righting moment when driving with powerful body movements.
With skipper and crew often presenting very different physical profiles, the hull and cockpit need to stay stable and balanced across a wider range of combinations. The aim is to let teams spend less energy managing heel and trim and more energy converting movement into speed.
Body pumping at this level is a technical and physically demanding discipline, using rapid, rhythmic movements to flex the sail leech and generate boat speed. The M10 is Mackay's answer to making that process faster, cleaner, and more repeatable for the crews doing it at the front of the fleet.
