Thin cracks in fiberglass on top of boat

[curious1]

I have a 260 purchased new in 1998 - I have recently noticed
thin cracks in the fiberglass. I have seen this on much older
boats. Anyone else had similiar problem and what can be done to repair and keep from spreading all over the boat.

If they are thin so you can not put your finder nail in them then I would not worrk about them. I have a 260 and there are a few. I have tried a few of the stop cracks products but in the end they draw more attention than they do help.
