DaveT, I have a Native Manta Ray 11 and a MR 12. The Ultimate FX is a great boat!Very high quality hull and fittings . Design retains a lot of the form and function of a canoe. The Hi-Lo seat is also very handy for adjusting stability and POV ( a 200 lb buck in the bottom of the boat significantly improves stability !)
If maneuverability is not an issue , you might consider the 15 FX or even the 15FX tandem which gives you the option of a buddy... noticeably faster hull to paddle and significant increase in load capacity. Only a bit harder to load .
