I don't think there really is a "do all" boat.
They all do something better than the next.
As far as flats style boats in new england, they're great to fish from, but they're FAR from being dry. Take a look at some of the older styles of boats that have been fished here for years and you'll see what the logic was.
Like QD said, if you can go without the trolling motor you can get ALOT more boat for your money.
Skip the outboard and get an inboard (little turbo diesel like they're putting in the new Makos etc.).
You'll save yourself ALOT of money in fuel costs, you'll still have tube and worm trolling speeds, and if rigged right, you can go right ontop of boulders and not worry about your running gear.
Also repair for inboards/io's tends to be less than outboards for no sane reason.
