First let me say they are both great boats. I just prefer the more modern look of the Belhaven over the Princess. ( Just a personal opinion )
Even if I added 10" to the Belhaven she would still be under 20 feet which is important to me with a v6 pickup. Like I said earlier I tend to overload my boat and some more area in the stern would help with my

problem.

The Belhaven also has slightly more head room and I like most of the cabin layout better. Not saying its better, but for me I like it.
The pictures of her at anchor shows her sitting pretty close to the way she should. That was at the end of a long trip and she wasn't carrying near as much stuff then. She also didn't have my lard butt in her. I raised the water line on her 1 1/2 inch's so she should be setting a little higher yet.
I also live in the land of rivers, Ohio, Cumberland, if you have ever done much sailing on rivers you know the winds ether on your nose or at your back. So we would have to motor more than we ever wanted to. The motor well would help quite the beast a great deal.
I used my boat a lot and very often for a week or sometimes two at a time. So on a new one I would want even more carrying capacity for a water tank and get reid of all those portable water jugs. A very large ice hold would be added too. A portable tiller table that could be stored in the lockers would be nice also. "Getting the picture I was making a 30 foot cruiser out of a 19 foot boat."
If a person was using her for a overnight-er all the time, and was much more conservative about what they took along I wouldn't change a thing. BUT that's not me.
