It is difficult to determine from the picture, even after zooming in (picture gets fuzzy). However, it appears to be black mold either on the surface or underneath the vinyl. The vinyl and the fiberglass gelcoat are both organic substances which mold growth is probable.

Recommend a weak solution of bleach (1:5/6) wiped on the vinyl to see if that will remove it - takes a few minutes after application. If not, the defect is between the body surface and the vinyl and the only solution is to remove and replace the graphic.

Again, this presumes it is black mold. If not, I can't offer any advice.
