The little lake we spent summers at when I was a kid was popular with
waterskiers from out of town on weekends. The boats pulling them would
sometimes make a turn right in the cove, in front of our cottage between
the shore and the moored raft we had to swim out to. Used to **** my
father off because us "kids" might be swimming in that area.

One day he came home with a bunch of Styrofoam "heads" that stores use
to display ladys's hats or necklaces on. He put bathing caps on them,
attached a line to them and the other end to half of a concrete block.
He put six or seven of them in the water near the raft. It worked.


I think that if you tied them up with "braid" fishing line it would
deter boaters after the first time.
