Thats exactly what I mean. That happened to me at a tournament on the Potomac River ,. We were running back to the ramp for check-in, of course waiting till the last minute. When I saw something go flying by. My partner said that the insert has come loose. Loose was an under statement. I wrapped the bow around the TM head flung the rest down the center of the boat and told my partner to hold on to it as we ran back to the ramp for check-in. I did get there just in time and did get 6th in the tournament with 18.83lbs. After getting the boat on the trailer the rail was easy to just pop back in, and there was no extra slack that I could see. It just keeps popping out.
