That’s a cute little aluminum boat. Polar Kraft, “Nothing Built Tougher.” That’s a pretty bold statement! No specs for aluminum thickness. Boats built in the Pacific Northwest have all their specs in sale advertising. My 22 ft Northriver Seahawk hull is 0.125. Boats built in the PNW are built to handle the nasties of the Pacific Ocean. Jet boats for skinny water, Snake River etc. Northriver, , Hewescraft, Rough Jet, Alumaweld just to name a few.
