Appearance of Blue Waterline stripe

I just "took over" 3430.  The boat was kept in great shape.  The original gelcoat is in OK shape, but the Blue waterline stripe is faded.  The body of the boat is yellow.  What are the correct options to restore the faded blue stripe to best condition?  Or should I just leave well enough alone?   By the way I Just joined the association.  Any suggestions would be appreciated.

I repainted mine with Petit enamel from the local marine store. The green "frog" masking tape seems to do a good job of preventing bleeding under the tape.
