Consider depth as a spec, too.
In FL and the South East corner of the USA, having a shallow draft boat is a pleasure. Your Uniflite is a little under 3' draft. The Defever 49 is 5.5'. That's a big difference.
I came close to buying a 48' Krogen Whaleback boat with 5' draft. A nice guy in Illinois said he was selling his because he wanted a shallower depth to do the loop and FL - it got me thinking. I went on a demo cruise on another Whaleback in Stuart, FL, and the salesman ran (softly) aground. He was very experienced, but just drifted out of the channel a little. I drift out of the channel a little, a lot!
Different regions have different conditions; in the NW, depth is not a problem. I love knowing I can come into an anchorage anytime and drop my hook in the open skinny water between the sail boats and the shore...
