Rule Number One- Always clean your hull with the softest cleaning media possible.

What that turns out to be is completely dependant on the age and condition of your anti fouling paint and how foul you have allowed it to become. You will not hasten fouling by creating "countless microscopic crevices." Fouling organisms will begin attaching themselves to your hull rgardless of how smooth or not your anti fouling paint is. But what you do not want to do is remove more paint than necessary during in-water hull cleaning. By using cleaning media (be it a scrubber, brush, carpet or whatever) that is overly abrasive, you will not only shorten your paint's lifespan but will introduce more copper into the water column than you otherwise would.

Clean your hull relatively frequently and gently. This is the way to maximize your boat's performance both under power and sail and minimize your fuel consumption and carbon emissions.
