What effect will the UItrasonic Antifouling system have on my fuel consumption?

A growth free hull will have a dramatic effect on the speed and smoothness through the water and will improve fuel consumption considerably. Consumption usually increases dramatically during the season as weed and algae accumulate on conventionally anti fouled surfaces. Speed can also be affected. This is prevented by your Ultrasonic antifouling system therefore you should save considerable sums on fuel alone and your boat speed should be maintained.
