Is this hull patched?

I inspected a used boat today and the boat has potential to consider making an offer, but I'm trying to determine if a mismatch in the gelcoat indicates a major repair was done on the hull.

If you look carefully at the exterior, there is a large area on the port side between the bootstripe and the gunwale, directly below the two large windows, where the gelcoat doesn't match the rest of the hull. When I looked behind the port settee, in this area, the fiberglass is quite irregular, and isn't painted like most of the rest of the interior of the hull. Am I correct to assume there was a major hull repair in this area?



The small wood blocks glassed to the hull support the settee seatback.


I requested a copy of the most recent survey, which I was told was from 2004. What do you think? If there was a major hull repair, I'm pretty reluctant to go forward with an offer.

several more full resolution photos are posted at the link below: there is one photo in this set showing "cracked" blue/grey paint inside the hull that is present almost everywhere else the hull is visible from the interior.
