Interior portside crack

[Augs]

I'm looking to purchase a 91 MacGregor 26S. I've found an interior crack (picture is attached) along the port side between the two windows where the wall and header transition. Is this a common issue with this boat? Likely to be a cosmetic issue or more structural? Otherwise she's clean and appears to have been well cared for. I appreciate your feedback and insight.

Is the liner really structural anywhere?

Fiberglass can be repaired. If the rest of the boat is a good buy I'd get it.

I failed to mention in the original post that I am new to sailing. This will be my first sailboat. I appreciate the feedback. Thank you.
