The flip answer is one that floats, to avoid, one that doesn't.
Seriously though it depends on what YOU want, I like a slow displacement craft that squeezes the most out of my cruising dollar. Accomodations have to fit within that framework. One of my buds is an ardent bass fisherman. Raw speed to and from the fishing grounds is his primary diciding factor in a new boat. Another bud is an old speed racer that was internationally known for breaking three speed records in one day. No accomodations there huh?
I have one boat that I love because it is a fish and ski that my son learned to tube on and still loves to take out.
Err, the very first question would be what SIZE boat did you have in mind? The feature set for a 16' skiff will be completely different from a 32' cruiser ...
Before we can help you with your question, some information would be helpful. Please add your location to your profile. That's a good start. What to look for depends a lot ... salt water or fresh? Great Lakes or small inland lake? Cruising 500 miles the Mississippi or just a couple hour's waterskiing? Do you have a certain body of water you plan to do most of your boating on? What kinds of boats are on it already? Is it a 2 1/2 month northern summer thing or a year-round craft for southern waters? Does it need to be trailerable or will it be slipped or moored when you're not on it? Are you a single guy, a young family, or more mature with occasional grandkids to use it? Sail or motor?
Every boat owner usually has more than one objective, so these don't necessarily have to be exclusive, but the more we know the better we can advise.
You have to answer a few questions first, then we can go on with advise..
1. $$$ you have to spend
2. Where will use the boat
3. How many people on board
4. Fish or cruise.
5, Trailer or dock at a marina
I can go on, but we need answers to help you.
