How short of the required 590cms is it? The last boat I had with a tiller pilot had the tiller "connection pin" mounted on a metal bracket that projected below the tiller. I've no idea if this would be a practical solution but I'm wondering if it would be possible to have this sort of arrangement but cranked down and away from the tiller (to port) to gain a few cms. Maybe in this way you could get the required 590cms gap between the tiller connection point and the cockpit side when the tiller was centered?
