I can almost imagine. I had an incident where somebody had a T-post attached to their boat dock. I cant imagine why unless it was to keep boats away from the dock, but it was under water where you couldnt see it. I heard the horrifying scratching sound and it made me sick. Pulled the boat out at the end of the day and yep, a big deep gouge in the side of the boat about 3 feet long.Jim EbarbMany, LA (Toledo Bend Lake)2004 Cougar/ 225 OptimaxHumminbird Helix 12 Chirp SI on BalzOut Mount at bowLowrance HDS 7 at bowHumminbird Helix 12 Mega SI on Ram Mount at ConsoleLowrance HDS 8 in dash at console
