Bill I agree that one tends to steer where they are looking. This happens even in a car. I think where the depth/chartplotter is located depends a lot on how the boat is laid out. For a boat like yours the lifeline would be a very bad solution for the reasons you mentioned.
With a wheel if you are behind it then having the depth/chartplotter on the pedestal is a great place to have them. With the Endeavour that is where we will have them.
I'm not so sure, Sum. I have long been an advocate of the "avoid the tyranny of being behind the wheel all the time" approach.
I have had two tiller steered boats for over 14 years, and now a wheel for 13+ years.
If you don't move the tiller or the wheel (currents notwithstanding, and even sometimes when they apply), if you don't move the wheel or the tiller and you keep the throttle in the same position, the boat generally continues to go where it was heading. In all cases there has always been a slight delay in boat heading changes even when you do move the wheel, but in all cases it is a LOT less than a car.
So, in all these years that I have been taking my eyes away from "the road" to peek at my trusty handheld GPSs, both the only-numerical earlier ones and then the smaller chartplotter types, I haven't gone off track much, if at all.
I simply find "needing" to have all instrumentation behind the wheel is very limiting to the enjoyment of the boat.
I believe there was an earlier post on this type of topic, and I recall you may have been in on that one, where someone showed a nice chartplotter arrangement that swiveled to allow use both behind the wheel as well as from the cockpit side. It was one of the very few I've seen of a good sized chartplotter installation that made any sense to me.
