Actually the twitching is very very minimal, only the operator would know it. I generally try to set-up my boats coming directly towards me in such away that they run a true straight course. If I take my eye off them after setting a course, It will not be a concern. Generally I am the only one sailing in this private pond. But, there are obstacles one must be aware of, such as rocks close to the shore, and a few patches of weeds.
