It's a not uncommon fault in many GRP structures. It's caused by shrinkage in the gel coat as it cures. The proper way to deal with it is to grind out the cracks to the underlying laminate and then refill with new gelcoat. A DIY quick fix alternative is
to open the crtacks out with a sharp pointed knife and paint over with a two pack polyurethane paint.0
