Abstract

A water-borne craft having at least two parallel rotatable float bodies, the general cylindrical form of which has at least two helicoidal turns which extend from the front end to the rear end and around an imaginary or actual central hub and which between them form two passages progressively diminishing in depth from the front end of the float body to the rear end.
