We had a Bayliner similar to what you described for about a decade on the SF bay. When cruising, I would typically be seated for the 90% of the time that is just relaxed. If there was anything going on, I would be standing up. Even something as benign as being in an area with a few other boats, I would automatically stand up to have the best view. The view was not restricted at all.
The one thing that was an issue is salt water. Once the windshield and isinglass got splashed a few times, visibility would be reduced because it leaves a residue. In the years I had the boat, I can only think of one time that the salt water was really an issue. We were headed into a harbor for an overnight in SF going through an area with heavy commercial and recreational traffic. I ended up having to turn around and just hang out for a few minutes until there was a gap in traffic that I felt comfortable with given reduced visibility. A bucket of fresh water over the isinglass and windshield helps out a lot.
