Hammer Super Yacht

Helicopters parked on the back of yachts is common these days (for some), having one lowered into your garage is far more slick. Super yachts also require their own personal submarine - and one that docks into the hull at that - if they are to be taken seriously. The Hammer has more than one submarine. The Hammer also has large re-configurable decks, so the fun stuff can be stowed away neatly creating plenty of party space with lots of terraces over looking the sea, and an underwater salon with windows that start above the waterline and extend way beneath it. There are also underwater video cameras that broadcast to the many large LCD monitors located throughout the vessel.

The Hammer's unique ability to house an enormous amount of toys and discreetly hide them with clever packaging solutions is one its greatest assets. Her high tech transom gives entrance to a dry dock that gives space to them.

The bow is widened no unlike an aircraft carrier in order to have sufficient landing space for the helicopter. The helicopter can be lowered to her garage from here.

The propulsion of the Hammer is based on a Francis turbine. The turbine case is installed horizontally, while the transmission comes vertically over a planetary gear. All this is turned by a radial diesel engine. The water intake takes place vertically over a big flat nozzle leading the water directly into the turbine case, where it is accelerated into the outer ring and guided out over the tangent pipe.

Steering is accomplished by turning the whole unit (engine, gearbox and turbine) in a radial cage. Both propulsion units are hydraulically controlled - due to the enormous mass they are connected to.

The Hammer superyacht was designed by Guido de Groot. De Groot has also designed cars for Citroen, namely the Xsara coupe.
