anyone seen this before or have any idea of the severity? i'm considering purchasing this boat and in general the boat is in excellent condition, very few penetrations in top side of hull, no bottom paint, only some minor scratches on bottom of hull, very minimal spider cracking ( looks like it has been under cover most of its life ), transom drains not corroded, etc.. all in all, looks like it was meticulously maintained; however, in this one spot, there is a depression or dent as shown in the pic. it is about 8 inches in diameter and just looks as if something pushed in the side. but there are no cracks, no other indication of a repair, discoloration, etc. when knocking on the hull, i can't feel any softness or hear any hollow sounds. i have inspected it closely and it just looks like this portion of the hull sunk in about 1/4 to 1/2 inch ( max at the center ).
i have an 1983 15 ft and know that very small depressions can be typical, but never seen anything this size.

if it is just cosmetic , i'm also wondering how difficult it would be to repair .
