Those are cosmetic and are from the screws in the rubrail. They are pretty common. Unfortunately many of the new boats get stress cracks because the resins just are not as good as they used to be, plus because everyone thinks they can smash a wave and the boat should handle it. In the second picture it goes through all the way to rub rail. It is not as expensive to fix as they make it sound on this forum. Send the pics to a couple of shops for reference. I had a few fixed on a Ranger and it was around 600 bucks. The guy guaranteed them for life, if they ever came back he would fix for free. They never came back, I had the boat another 2 years. If you have a good glass guy, they can repair them.
