Bottom Cleaning : AquaTLC cleans your boat from waterline to the bottom of the keel, including all running gear, trim tab(s), shaft(s), transducer(s), knotmeter, and intakes. A clean hull gives you better fuel efficiency, higher speeds, and a longer life for your boat. When performed incorrectly it can introduce high levels of copper and biocides, such as cuprous oxide, into the water. 

A hull can be painted with either hard (low copper) paint, or anti-fouling paint (often referred to as an ablative paint). Hard Paint will be slicker, and will allow your boat to move faster through the water. However, it will require regular hull cleanings to remove the slime coat and keep it free of marine life such as barnacles. This type of paint has less tendency to come off during hull cleanings.
