Magnitude 80

"Magnitude 80" incorporates the latest developments in yacht design to reach the client's goal as the
fastest boat to be based in the restricted draft of
his home port. All-carbon laminates combine with a
canting keel to keep
displacement to a minimum while a retractable forward dagger board dramatically
reduces offwind drag compared to rotating canard
configurations. Drag is further minimized with a
retracting sail drive
and all appendages - keel, bulb, dagger board and rudder are carefully optimized with
the latest CFD tools.
