I second the question on where you are planning on fishing. I think there’s a fairly small amount of lakes in MN where you have to worry about 4′ waves with any regularity(LOTW, Mille Lacs, Superior, etc.).
If you are planning on buying a boat to primarily fish those waters, I think a mod V is just not the right decision.
But I’m kind of a wuss when it comes to big waves in big water, it’s just not anything I ever want to mess with just to catch a few fish.
Can they handle it? Sure, and a geo metro can tow a Ranger 621, but it’s just not the right choice to do so. They used to commercially net fish on LOTW decades ago in small aluminum boats, in just about any weather condition. Those boats are capable of doing the job, but they also lost family members doing that work.
