Opinions on this welded aluminum hull

[Robbyracks]

Hello folks,

I am considering this 2000 Crestliner 182 model with a 150 HP Etec. I am a little concerned about the hull (only seen it in pictures/videos). Before I put an offer in and test the hull, I want to get some feedback on what I am seeing in these pics.. it appears that fairly visible lines have emerged along the hull running parallel with the length of the boat. I have never owned a welded hull.. I've read that this could be "oil canning". I have a video too if that helps.. Thoughts? TY

That's just where the interior structure is welded. Nothing to worry about, every welded boathas those.

Sign on the side says it all Great Lakes Outfitters that hull has run at full throttle for hours over rough waters, I would pass.

You can see the same thing on this 2024 cresliner I'm doing. You'll have to zoom in a bit, but you can clearly see regular straight lines.

This happens when an aluminum hull is drive hard thru chop. The continuous pounding causes the aluminum to take this shape. You can also find this on riveted hulls, but the welding process makes the aluminium m more maleable and easier to reshape. As long as their are no cracks on the welds or cracks in the skin, it is not a problem other than you know the boat was run hard. Many folks look at those as abuse and will drop the value as it makes the boat harder to sell. If it were me, I would look carefully at the welds to be sure none are cracked, otherwise, can you live with the bends?
Is the boat priced with those marks in mind ? I have owned aluminum boats for well over 60 years and have never had that on my hulls, but then again, I care for my boats very well.....
