Corrected entry: In the scene where Norrington is watching Will and Jack through his spyglass as they get away on the Interceptor, Jack is telling Will to do something, and Will is holding onto two lines, swinging them back and forth uselessly. This would not cause the boat to do anything, such as turn, or go faster.
Correction: Jack and Will aren't actually trying to take the 'Dauntless', but only trying to make it appear that they are so they can take the 'Interceptor' when Norrington comes after them.
