I'm looking into the possibility of acquiring a folding canoe for future trips.  I'm looking into this option for two reasons:  long distance travel to canoe areas and fly-in trips where more than one canoe may need to be transported.  I and my normal paddling partner both paddle identical solo canoes so the hull-within-hull option is probably not going to work for fly-in transport.

Specifically, I'm looking at products made by Pakboat (US made from what I can tell) and Ally (Norwegian made).  Both have very similar designs except that the Pakcanoe has inflatable floatation tubes along the sides, while the Ally has a "floatation" mat on the canoe floor.  Both are "material on frame" designs.

I understand that the design has drawbacks including being less efficient over water than a hard-shell and the potential for bending the aluminum frame tubing.

Anyone with first-hand experience with either of these two choices.  BTW: I'm not particularly interested in "between" designs or kayaks of similar construction, mostly due to gear loading and weight issues.

Thx,
