In sailing, it is the task of the grinder to transform wind into propulsion by hoisting the sails as quickly as possible.  Grinders perform the backbreaking work on board- they are truly top athletes!

Exerting physical strength and endurance, the grinders race to turn the winches on sea-going yachts to raise the sails, with a classic crank motion.

The NOHrD WaterGrinder brings this intensive sport to your home, enabling you to achieve the impressive fitness levels of a racing grinder, without having to forego the element of water!
