Consider Obstructions and Water Movement in the Area
Consider any obstructions, such as structures or boats, that could slow or stop the flow of warmer water at
the surface. Natural currents move de-iced water downstream.
Some useful tips are:
•
Work with the current to de-ice from the upstream side.
•
Use the design of a boat to push water from the bow to the stern. Fully protecting a boat often requires
more than one de-icer.
•
Angle your de-icer from the deeper water toward shallow water.
•
It is better to angle multiple units in one direction, creating a current, rather than in opposing directions.
•
In tidal waters, place the de-icer so that it is in shallow water at low tide and deep water at high tide. If
you are protecting a boat, tie the de-icer to the boat so that both rise and fall together with the tide.
