Thanks for you comment JeffH.
I think Denr had good advise, but for some reason he lost it. (I think he has his boat on a mooring in Milwaukee and we have been having a weed problem in our harbor, esp. bad in the mooring area. Its hard for some of the people on moorings to get their boats out--maybe we should cut him/her/it some slack).
Jafeica was not a suggestion for a name, I just thought it was funny. BTW, the name was on a motor boat. Kind of typical of a motor boater.
