I've been reading the Boat Docking by Charles Low. Good stuff.

He suggesting practicing manuvers and getting a feel for how the boat
responds. We have a calm lake nearby and I'd like to practice there.

I'm thinking that setting up some marker buoys as the "dock"
or as points of reference would be good. But I'm worried that
if I tie something that floats to a weight the rope might get
caught in the prop if I end up going over buoy.

Any suggestions??
