As a 2520SC Mod-V owner ("01) I have to say it's a tough call. The MV does pound in any sea at all. Mine maybe more than others with the Volvo 5.7 (350 Chevy) and Duo-Prop outdrive hanging all that weight off the back. And the pilothouse helm being further foreward than the center consoles I've had before takes some getting used to. Plus the hull is so solid there is absolutely no "give" to soften the blow. But if you slow it down a little and learn to work both the the trim tabs and outdrive, it can be reduced to a level that can't be called smooth, but acceptable. I have never felt it was a large problem, especially after I went way out with a few friends who had larger big-buck Center Consoles and they slowed down too. I did hang with them for a while, but slowing a little more was a much better ride for me. But I'm talking only 3 to 5 MPH.
In return, the MV will use way less fuel. I don't know if it is the Fuel Injected 350, the Duo-Prop or the MV hull, but I get great milage from my set up. Much much less than the twin powered boats I run with, but close to the lighter single boats with the new Yami. Suzi's and Evo's I talk to. But I don't horse it hard like they do. It is way more stable bottom and drift fishing than any boat I've had, but it may be the beam, weight or hull as I have never been on a DV Parker to compare it to.
So you pays yer' money and takes your chances. Truth is, f I lived where you do fishing the canyons, the DV is a no brainer if your serious about going out in anything but a calm day. But If a good deal comes up in a MV and you can understand the compromise your making don't be afraid to buy it. Hard as you choose to pound it, you ain't gonna break it.
