Your best bet may be to just ask her, as she probably doesn't want to be measured.....or maybe she does....anyway, the charts that are used for STRIPERS are troublesome.

Our totally unscientific but usually correct observations at a Cape tackle shop are that years ago, a 36" fish weighed 20 lbs. every time. Today that fish will be lucky to make 17 lbs.
