For antifouling protection on aluminum boats and underwater metal parts you have to apply a copper-free bottom paint. Inflatable boats made of PVC Hypalon or other materials also need bottom paint if theyre left in the water for long periods. The downside to these paints is they are not as effective as ablatives and the paint stays on the boat and requires more aggressive sanding.
They require more maintenance to keep the bottom clean. While they are far more effective than a bare hull a hard bottom paint. The majority of AL boats are painted for looks not protection from corrosion.
I left the entire bottom bare on my current 18 SS project and just painted the sides.

Most bottom paints today are copper-oxide based and cannot be painted directly on metal especially not on aluminum boat hulls. Applying copper-based paint directly on aluminum can lead to severe galvanic corrosion causing the aluminum hull to corrode into aluminum oxide powder.
The result can be seen on many aluminum pontoon boats or jon. If youve got a steel- or aluminum-hulled boat you likely know that you cant simply slap on any old bottom paint especially one containing cuprous oxide. Copper-based bottom paints interact with metal-hulled boats when immersed in water causing galvanic corrosion that can result in.
Dry sailing means they pull the boat out of the water after each use. Even in our part of the Hudson which is brackish to salty - tidal we can get nasty barnacle growth that without anti-fouling paint would be a major headache. VC 17 seems to be the paint of choice for fresh water but we use an ablative paint that discourages barnacles.
