I don't know what comes over people at a boat ramp. One time I was launching and I took off all the straps at the top of the ramp and for some reason I decided to also unhook the boat from the winch. I get back in the truck and start backing it down the ramp and realized what I'd done. I E-V-E-R so gently put on the brakes all the while watching in the rear view mirror. It looked like it was going to hold, so I applied just a little more pressure to stop completely but that little bump was just enough of a jolt to start it off the trailer about 5' before the water started. All I could do was watch as the boat slid all the way off the trailer and "WHAM" right onto the ramp. Up until that day I had, had a dry boat. From that day on I've had a small leak that I'm pretty sure is from around the drain plug. Fortunately, I still had the motor tilted up.
