Posted this somewhere else, but It relates to you question:
I have learned about the difference of the different Parker hulls somewhat inadvertently, so I don't have to defend my choice in order to defend my boat knowledge studleyness, so let me give you what I learned for the tuition I paid.
I ran across a rather well off individual I had done some work for and found out he had a 2001 2520 Sc that he did not use much. It was on a lift behind his house here in NE Florida. I ended up buying it for a very reasonable price. (This is the part where I got my education). He said it had been on the lift for a year, ran great and told me stories about going 50 miles out of St. Augustine to the drop off and back home 20 miles South on the ICW using about a cup and a half of gasoline. Something like that that I blew off as BS.
It had (has) a 5.7 Volvo/Penta DuoProp (Fuel Injected 350ci Chevy) with only 150 total hours on the Hobbs! Well, not related to your question, it turned out it had sat on the lift for over 4 years. Without being flushed. Or ran. Six months and $8k later I got all of the bugs out of it, not to mention corrosion seals and dry rot, and after running it hard up and down the Intercoastal for a month, was confident enough to take it out the inlet. Happened to be a little rough that day (3-4' ).
I had to back way off to keep from losing my fillings. I'd been in some rough riding boats, but you could tell this one pounded more, and you knew it was partially because of how it was built like a tank with no "give" in the hull to soften the jarring impact. I really wasn't expecting that.
So I started researching the boat (yea, I know. A little late) and found there were two different hull configurations, deep V and Modified V. I had always thought of Parkers as a deep water boat, didn't know there was this option. So I called the factory, gave them my # and confirmed that mine was indeed a Modified V hull.
Now concerned about my investment (Working Class Do Without type), I asked the older gentleman on the phone if I had bought a Bay Boat. After a moment of silence (I may have heard something like sizzling bacon for a second), he said "You live in Florida, right"? Yep. "Next time you have a Hurricane, go offshore, strap yourself to my boat, and when you come to, you'll be floating!" OK, good enough!
So the MV hull pounds. More than most, but that's what it's built to do. Every design choice you make comes with a compromise. The choices you make are most apparent on boats and airplanes. In the words of Bob Dylan, " You give something up for everything you gain. Every ounce of pleasure got a drop of pain. Pay for your ticket and don't complain." (Sylvio, if you care)
In return for having to slow down in the rough, my boat will cruise at 25 MPH on 2.5 GPH. That's right, 10 MPG. Yea, I know. I can hear the old salts screaming BS from here, and I haven't even hit the return yet. But I swear it's consistently within spitting distance of that depending on load and seas.
So I've gotten used to it. Buck up and learn to enjoy it. I know it ain't gonna' break, it WILL get me home, and it thins out the guys that will go out anytime to the real fishermen. It's a strong boat. Be a strong man. And it helps if you wear a cup.
