I demoed a CD Stratus last week at the Bay Area Paddlefest. I am interested to read any other reviews of this boat.
My sprint speed was the same as my Seda Glider at 7 kts. The Glider is 19’ long and typically races in the class above “standard sea kayak class” where the Stratus would be. The initial stability was very poor but the secondary was good. It seemed to have much less drag at crusing speeds in the 5 - 6 kt range than my Glider. I didn’t test the boat in heavy seas but my guess is that the very low volume bow would make for a wet ride.
