I can't seem to get into the archieves so I'll ask here. Beside the obvious (how far has the line moved)has anyone come up with something to let you know the relative position of the centerboard (all up, all down, halfway). Yeah, I know, I'm trying to make it more complicated than need be, but I have some VERY shallow areas I pass over, also narrow, and I'd like to have as much control as possible without banging the board.Fair winds,Bill
