I'm sure its like any "opinion" related question but,,, share your thoughts on bottom paint for an aluminum hull yacht. Price v Performance.
Since you mentioned price vs performance, I second @rtrafford's answer, Trilux 33 is a popular cost effective choice especially if you operate in warm waters. That said, in colder waters, growth is typically slower so you may not need as aggressive an antifouling(any local brand will do), but you still need an aluminum-safe copper-free paint.
