I'm in the market for something 16-19 feet. All three of these seem to be fairly seaworthy for coastal Lake Michigan voyages. The Ranger and the Mariner would certainly stave off 'two-foot-itis' (for a while). But the Newport/Gloucester 16 seems to be a little simpler when it comes to rigging (just looking at online images) Is that a worthwhile advantage over what you wouldn't be getting in the other two? I'm not concerned about seating numbers or sleeping more than 2 aboard.
