The biggest issue I have with view from the boat is that it can be hard to see submerged rocks straight ahead that are close enough to the surface to hit the boat. Sure I can zoom all the way out, but then they're still hard to see because the view is too far away.

But then again, that's not unrealistic... And it gives a 2nd player a job, to watch for that! (which is something we in fact do when there's more than 1 of us on a boat.)
