I have seen it and it is a monster.

It was located in Ecole de Voile Sansoucy, The catamaran school owned by the owner of Mystere catamaran

It had hydraulic motors and and hydraulic direction and it had a lifting mechanism like a cissor lift

It is not very fast but it is perfect for these old heavyweights like the Mystere 6.0XL, the Hobie21 and the old Hobie 18.
