Bought one for the wife because seat comfort was important and it has a good seat. When I tried it, I decided to get one too. It turns on edge just fine in conjunction with the right paddle stroke.
My plastic Looksha V is heavy, slow to get moving but it will do for day trips. Haven't tried it in big waves or wind yet, but I'll let you know when I do!
This is not a step up from the Looksha IV. It is a complete re-design.
I found this kayak to be a bit of a slug. It tracks fairly well in almost no wind, but doesn't respond to edging, even extreme edging.
The seat is comfortable. The seat back came apart on me the first time I did a rescue in the boat. The foam came off the plastic, the seat back came off the adjustment bars, and the adjusting straps became twisted and stuck.
It is a roomy kayak, a very large person can fit in there. It goes straight in calm conditions. That's where the sea kayak portion stops.
The right thigh brace came apart when I did a couple of rolls. Flimsy to say the least.
I picked up a Looksha V from REI along with an Elaho HV. The Looksha V is very stable (as stable as my Tsunami 145). The cockpit fits very nicely and it is great for a nice relaxing paddle. I found it to be a slow paddle though. It took a lot of work to get it up to speed, and then it dropped speed very quickly once I stopped. Maybe I am down on the speed because I am comparing it to the Elaho HV, which is very fast and paddles almost effortlessly. The other thing I don't like about it is that it sits high out of the water and wind cocks with the slightest breeze. Using the rudder is almost a must with any wind. Secondary stability appears to be good, but it is a dog when it comes to turning.
The flip side is that my wife loves it. She is a slow, see the sights kind of paddler and it fits her perfect also. Also, it seem to be a very high quality build, though heavy at 65 lbs. It is a good kayak for the price we paid and we would have had to jump a few hundred more dollars to look at anything else comparable like a Tempest, so we are content with it.
