Super Jet when buying a SJ?

[Superjet301]

I'm looking at another RN for my second ski and the bottom of the hull has some questionable places on it. But says it doesn't leak and doesn't look to be repaired but may have im not sure. Here are some pictures Please let me know what you thinks going on here.

It could be Yami-rider ill ask if it ever had tubbies at one point.

In the photo it looks like it has tubbies or sponsons of some kind installed right now, looks like the bottom edge of the ski is wider then normal.

Doesn't look bad at all. Nothing a little Marine Tex won't fix.

That wouldn't be a thought in my head if the price was right and I wanted to rip! That looks like the thinner R&D race tubbies maybe? I had a ski with those and they did that but never ever got worse....
