Hey guys (and gals) I ran across this last night and while it doesn't apply to the V20s (at least I don't think it does) it still seemed like interesting reading, if not a little scary for those of us who may go out on other people's boats that are a bit newer.

This article made me appreciate my older boat even more despite needing to do some repairs!
