I have had a number of bass boats and fish bass much of the time. One thing I would offer is bass boats are usually designed with a very low profile and as a result in rough water they can be a wet ride. Walleye boats tend to be deeper and have better rough water charactersitics. They can be used interchangebly of course, but there are comprimises when doing so. Bass boats will give more speed with the same engine on a Walleye boat. Either boat can be used for fishing most anything, depending on conditions at the time.
Just my $.02. Oops Musky’s same thing.
