The Voyager, Northwood Solo and Magic are all very different boats.  The Voyager is 17'6" long - a huge solo boat.  It's designed to carry a big load on open water.  It has zero rocker, which means it's very hard to turn unless you lean it on its ear.  If you want a straight-tracking freighter, it could be your boat.  If you want a solo that you can use in smaller water, look for a boat with a bit of rocker and at least a foot shorter.
