They were banned because of the huge cost, not because they didn't work. It's been a long time, but first they required the boat to be dry sailed since any growth at all on the film (even algee) made them worse than bottom paint. And as I remember it the dry sailed boats had to replace it every couple of days too.
No one wanted this to become part of the lexicon, it was just too expensive, and the gain was enough that it really mattered. Basically it added $1,000/day to racing, and those who could afford it got a massive gain, but even the people who couldn't afford it didn't want to pay that much
