I did a demo day at my local outfitters paddling spot on a calm lake. I tried several brands sit inside and sit on top kayaks of varied designs. I liked most of them but I fell in love with this kayak! It is very responsive- super fast up to hull speed which is pretty fast and efficient , so much I was pleasantly surprised, the cockpit is very roomy, very comfy seat, it tracks well, it's very stable ( initial and secondary stability are both excellent), it just felt right immediately- I have a fickle lower back ( chronic moderate to severe lower back pain) and the cloud 10 lawn chair style seat in a good performing kayak is a home run Eddyline! I immediately went to my local shop and bought myself a blue over silver Eddyline Sandpiper 130.
