I used to fish MA6 out of an old 21' heavy fiberglass boat and did well. Ideally, you will make a few friends and go out in their boats before you write a huge check for your boat. Over there, it will be much harder to find used boats to buy or sell compared with Puget Sound.
If it were me, I would be looking into 22-24' aluminum with a nice comfortable cabin with diesel heat. That would get you just about anywhere under most conditions as well as being able to adventure up into MA7 which is incredible in the summer.
