There are various 'gelcoat safe' pint removers available from most marine suppliers... on WOTAM I 'erased' mine with some rubbing compound and elbow grease. Some light 400 grit wet sanding followed by rubbing compound probably would have been a bit quicker.
Just remember if you try to compound them off, the compound may work faster on the gelcoat surrounding the paint than the paint itself. I'd probably try a gelcoat-safe paint remover.
Interstrip 299E. I think it's by Interlux. It's little expensive but gelcoat safe, strong, and even takes varnish out of the gelcoat with a brass bristle brush. A little elbow grease required but won't cause damage.
