According to Capt. Henk Hensen, in the book “Tug Use in Port”, which sentence is WRONG when considering the disadvantages in use short towline when towing on a line?

the shorter the towline, worst will be the absorption of dynamic forces and bigger will be the peak values of towlines loads.

the towline strength should be capable of coping with the static forces that is higher for short towlines.

when using short towlines, the friction force is very large, resulting in high temperatures and considerable wear so imperiling the towline’s life.

when a tug is made fast as forward tug and is operating broadside while ship is moving astern, a short towline has a negative effect on tug safety.

shorter the towline, bigger will be the wash effect, reducing pulling effectiveness.
