Yes - survival suit is a must. Too bad my boots didn't float.
Only if someone was there to witness it and record it, this certainly would have been a youtube hit. Normally I drive the boat off or push it off but the trailer dropped so fast, I hit the brakes and sprinted out with precision steps such that I was still knee deep running along the trailer frame to the bunks to catch the bow of the boat. Even I was laughing as I was in the process of catching my boat......hard to stop a 19' boat when it wants to go the other direction.
