According to the pilot, upon arrival at the airport, they observed the windsock indicating the wind was from the north at 15 knots. He performed a no-flap, straight in approach to runway 35, and the airplane touched down just before the 1,000 ft runway marker. After touchdown the airplane veered to the right of the runway, and he attempted to correct back to the runway with brake and left rudder inputs. As the airplane continued off runway heading, the pilot initiated a go-around and was about 5 to 10 ft above ground level when the stall warning horn annunciated. The pilot reduced back pressure, and the airplane touched back down on the runway. The pilot stated that he had insufficient braking after touchdown and the airplane exited the runway surface and struck an agricultural ditch. The airplane sustained substantial damage to the fuselage and right wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
