The seat was comfortable for 4-5 hours of paddling. It was nice and stiff and with the integrated rudder could turn very swiftly. It is fast and quiet. We paddled in the creek and the harbour. Primary stability was fantastic. I didn't push it any further than that.
Bottom line is that I have ordered a 532 and can't wait to get it. Beautiful looking boat and handles like a dream. Can't wait to get my boat. Looking forward to all the new places I will be able to explore.
I will update this review when I get mine and have taken it out a few times.
