Yeah, the problem with barnacles is that you start getting significant
encrustation in as little as a month of warm seawater exposure.  The
little suckers are ubiquitous and attach themselves in hours, grow in
weeks.  We dropped a lawn chair in the water by accident off of our dock
last summer and hooked it and reeled it back in a month later, already
partially covered with barnacles.

There are paints and chemical compounds and so on that are "resistant",
but dealing with them is still an ongoing battle of boat owners etc.
