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.
