Scratches in gel coat on composite hulls appear white and the stems of RX are often much more rounded and blunt compared with sharper entries on most composites.
If those four were the only photos the seller furnished, I'd ask to see more before I drove any distance. Especially closeups of the ends and seats. A shot from one end showing the full length of both rails is nice, too, as any deformation of the gunnels will be obvious.
