Definitely! Later in the war, when surfaced, the crews always needed to have one eye on the sky to check for planes. And even later, it was virtually impossible for a U-Boat to be on the surface, especially after the Allies improved their radar and closed the air gap.
We can be grateful that Germany lost the tech war in the Atlantic. That, coupled with the ability to decode German radio traffic, was the end of the U-Boat.
I think SHIII, with GWX, models this very well.
