EBarnacle here. My kayak is very stable also. However, most kayaks are dependent upon the paddler's posture to stay upright. I have seen really skilled paddlers do handstands in K-1's. I can barely keep them upright. Most ocean kayaks are skinnier and have less initial stability in stable 2 [that means upright] than in stable 1 [flipped over]. The parameters of stability can be very narrow. This is also why so many skilled kayakers wear wet or dry suits when on [hopefully not in] the water.
