"Despite the proximity of the mirror to my eye, the view is still quite limited, so it is necessary to move your head around to check the wider view of approaching impediments. The added problem is that everything is back to front, so all your head movements need to be reversed to obtain the necessary information. This then has to be translated to pulling on the oar that will move the bow of the boat the other way to the way you are seeing it as you are not only sitting the wrong way round, but looking backwards as well and having to move your head rather than your eyes as they need to stay fixed on the mirror and ingnore the oscillating view astern, in order to scan the scene ahead.I have never really liked mirrors. They don't give a good enough idea of what is ahead so you have to look round fairly frequently anyway. The closest thing to a useful mirror is on the Clovelly Scull, where it is mounted on a bipod mast so it is just above your head, so you get a good view straight in front which is handy for both navigation and spotting immediate peril. The mast is also a good place to mount a GPS.
My ageing grey matter could not cope.
Not even slightly."
This is Paul Zink demonstrating it.
