also try using Barkeepers Friend. About $2.50 and does the job.
But ots all short term success.  The gelcoat surface becomes pourus when old and the only real permanent cure is a new paint job at the emd of the day

Guys : Barkeepers Friend has Ocylic (sp?) acid in the powders form.  FSR (Fiberglass Stain Remover) has the same acid in the gel form. 

I was much happier when I moved the water line up - because that small white strip was usually under water anyway (hence the stain).  That's why Gerry Douglas told me that the 3ft+ draft (wing keel) was a design goal which Catalina missed!!  The real draft (C34 loaded) is closer to 4ft 5 in.  So you might as well raise the water line anyway because the boat sits lower in the water than the gelcoat trim was designed for!!!  Save yourself some work each spring!!

My thoughts exactly.  I think if you don't have 2-3 inches of bottom paint above the static water line, consider moving it up. Think painting the white would work.  Really, IMHO, the only ones that get a close look at the hull below the boot stripe are fish and seagulls.  Not the usual sort that I try to impress with a bright white stripe.  Lots of other things much higher on my priority, much to the chagrin of the fish and seagulls. 
Sorry if I sound dismissive but really it's only obvious when the boat's out of the water.
