Antifoul

Are there any new good anti foulants on the market for a 30ft high speed cabin cruiser?

if you check locally what everyone else at your moorings is useing it might be better.because conditions differ from harbour to harbour.and the most expensive is not always the best.i found this out last year.

I Have been using an antifoul called awl grip > my boat is in the water all year when I take it out in march she is only very lightly fouled. It is expensive 250 euros a gallon but I get 3 seasons out of it. My boat is a bayliner Trophy she is 22 ft. long
