11:50 - ‘Multiple-hybrid’ performance 40- foot cruiser Joso Perkovic, independent designer, Hreko, Netherlands HReko 1ooo is interesting as a base for development of the perfect 40-foot versatile hybrid cruiser. It is a ‘multi-hybrid’ sailing boat, a hybrid between a trimaran and a performance monohull with water ballast, which results in an entirely new and improved type of vessel. The ingenuity lies in the fact that floats (effectively bilge keels) and ballast tanks have interchangeable functions as needed. The philosophy behind this project is as follows: if you’re dependent on wind and electrical power, your boat should not be heavy. Wp solar panels: 1.5kW; hydrodynamic regeneration: 3kW; generator: 6kW; batteries: 20kWh.
