New Name!
When we acquired our boat in '94 it had a large painted name on each flank and the hailing port on the stern using mylar letters.
Acetone took the paint off, with patience, and a lot of rags. The gel coat was new, underneath, and took a few years to fade to match the rest.
Transom was worse... lots more UV damage to the gel coat back there. AFAIK the surface of the gel coat actually erodes slightly over the years and under the letters was, of course, original "height."
For years the original hailing port could be read, barely, under certain flat lighting conditions. After some buffing and waxing it's 98% gone nowadays. :nerd:
So, cautious removal and then patience may be a reasonable tactic.
(And, do not use steel wool on the exterior of your boat.)
As to renaming, here is a good ceremony:

You might ask Glyn J for expert re-naming advice, too!
