Of course, the preceding remarks apply to clear water and will not hold good where the water is con- tinually agitated and clouded by mud or refuse. Swirling water usually indicates a shoal or some submerged obstruction or may be the result of a divergence of current.

When ready to cast off from the mooring, haul in the slack on the dinghy's painter to prevent the bight from dropping into the water and fouling the propeller. Test the engine to make sure that it is running and that the clutch is workin g properly, and let go. Allow the boat to drop back from the mooring enough to allow you to clear it and then start ahead, taking care that you do not veer off so sharply that the stern of the boat will foul in passing the buoy or dock.

A little extra care and attention when laying ft up for the winter or even when it is to be out of commission only a few weeks or days will prevent a variety of troubles later on.
