Well...tried to make a scupper hole cart and quickly found out that wouldn't work with this boat.

Improvised to a strap cart which works pretty well. Kinda low but not bad.

Nice work. I just swapped out to a new seat (Expedition). So much nicer on my back. Makes me feel stupid for not doing it sooner. 

I've got same yak but angler edition.  I need a seat upgrade but had issues finding one that fit seat well due to low ride and seat being so narrow.  But it IS hella stable!  What seat exactly is in ur pic?
