Mine is copper coated Chris, no growth after a year in the water, just a thin layer of slime that washed off with a pressure washer at service time .
My thoughts on your boat, if you are going to lift it regularly, which I did with my explorer , you might want to check the effects of the trailer on anti foul, copper coat is hard epoxy resin and won't be affected by rollers etc, so I'm told , and it lasts ten years, now I'm not bothered about the costs so much as the inconvenience of having to lift and clean and reapply this stuff every year or two , I read up extensively on coppercoat before I ordered it , it has been on some boats or well over the ten years , there are some bad reports about it as well though , but the way it is applied will affect its performance , basically it is copper granules mixed in with epoxy resin and painted on to your hull, the amount of copper is what makes it effective, too little and it won't work as well , too much and it's illegal I believe , for environmental reasons .
One other thing about it, some say it needs a light abrasion at each lift to expose the copper , coppercoat told me to leave it be, this is my second year in the water with it applied, I left it alone when she was lifted, no abrading, so well see next year if its still as good.
Personally I'd get your boat coppercoated so I could lift her regularly for cleaning, it's so much easier to clean on the hard and I'd be worried about traditional anti foul rubbing off whilst doing that.
