I have found the aluminum only antifouls don't offer the same protection as due to the lack of copper. I use it on by leg and when I slip the leg is always covered in growth and barnacles. The hull only has slime and a few barnacles around the water line.
I would use International Micron Extra on the hull if you want good protection for 12-18 months
