Your photo shows the common problem of "green line separation".
Dick Fisher wanted to advertise how thick the fiberglass of the hull was so they did not gelcoat the outer top edge of the transom on the classic 13, 15 and 17's up until the 1990's.
If it does start to split open, not every boat has it, but MANY do, the recommended repair is to insert epoxy and clamp. Seal the entire edge.
