I just got this and took it out on the lake for the first time 4/27/18 (also this is one of the first trips of the season). It felt very unstable and tipsy the first few minutes! It also felt tight/smallish, I am 5'2" and 140 pounds. After some time in it, I realized I needed to engage my core muscles more in this kayak than my previous one and that gained me a great deal more stability. It handles very well in the water and after a few hours I became comfortable in it without it feeling so small. I'm looking forward to more time in this to adjust to it. It's enjoyable to paddle. I do think I'll end up in the drink tho at some point bc stability appears to depend significantly on my balance.
On first trial it felt relatively unstable & I wasn't happy about not being able to have my legs in several positions - am 5'4", 160 lbs. - but second time I got more used to it. I then paddled several more times last summer and loved it. Easy to get in/out and I found I was able to bend one leg if I wanted. It seemed as fast as a couple of other slightly longer rec boats I have.
I used on small/med lakes, and a flatwater river. Best for day trips. Seat comfortable. I bought a Seals cockpit cover (size 2.5) and splash deck for it, which worked out great. If there were a bit of chop, water would have easily gotten into the boat because of shallow depth but the splash deck helped. I don't paddle in rough weather or real far from shore on large lakes - if so, would prefer a sprayskirt.
