I believe you're correct Dave, which is kinda why I brought it up. Not all go fast boats use the bonding, and I won't bring up the popular one I know of that doesn't
I don't think it's quite as bad as people are led to believe though. I may be wrong, but I think Cobalt and some others use reinforced marine plywood or something like that to fasten the screws to. I remember seeing a Sea Ray involved in an collision where the side looked like tarpaper that had been ripped.
At any rate, I was just trying to dilute the impact of the brand new poster's statement (one post only?) as I just knew people would get the wrong impression from what was most certainly intended to deliver maximum impact. Sometimes we forget that many people haven't been involved in boating that long, and many more know very little about the inner makings of boats. I should include myself in the latter category as I learn something new everyday.
