Crazing above the hard chine

[Fr. Frank]

While putting on a new bootstripe, I noticed my unrestored '72 Seafari has crazing in the gelcoat just above the hard chine on both sides, beginning about 3' back from the bow, and continuing for about 6'-8'. I presume this is from hull flex over the years. Guy's, I know a little bit about engines and rigging and performance, but I know NOTHING about fiberglas and gelcoat, and epoxy paint, etc.

My transom and decks are solid, no soft spots or flexing apparent. I DO have separation between the liner and the hull in the cabin on both sides, to the point of having a 1/8" gap appear on both sides between the liner (at the cabin V berth)and the hullsides whenever I ride over a boat wake or other short and steep chop. I discovered this a couple years ago while my wife was driving in from 30 miles out and I was trying to get a nap.

Is this indicative of a serious problem? Is it a cosmetic issue? Should I run in circles, scream and shout?
