How often do i need to have my GRP fourwinns antifouled every 12 mouths or every 24?

Question

it;s the first time i've had a boat. i had her antifouloed last year when i got her. This year i have brought her out of the water, he anti foul is intact and the weed came off with a pressure washer. however my man who does tells me it needs treating every year, which contradicts his statement last year when he said it would last for two. i feel he may be asking for work for the sake of it. It's costing around £400 $800 so i don't want to do if it's not nessesary. Help graitfully received.
