All Rhino Boats hulls are constructed of .125 marine grade 5052 aluminum. There is no wood in any Rhino Boat. Hardware is stainless steel and all wiring is under the floor through PVC piping. Every Rhino Boat has a double welded hull (with 10 year limited warranty) to make an all welded hull with no rivets to leak. All carpet is marine grade outdoor carpet. We make a 48, 54, 60, 66 and 72" bottom with either a 125 or 190 thick bottom.  We can glue UHMW on the bottom of the boat and paint the boat to your specifications.
