Cita:
"The Volvo held fixed blade propeller decelerates - theoretically - the yacht from six knots under sail with over 200 Newton. To the measured total drag (approx. 550N) of the yacht at this speed, one must then still add 40% ."Braking contribution". With the propeller free to rotate the drag is reduced by at least 50% to 100 Newton. " Es decir, la hélice fija ofrece el doble de resistencia que si la dejamos libre.
