Raft Boat
You might notice the original copyright year of 1999 was changed to 2011. This did receive a small change at that time. They also dropped the "Whitewater" part of the name. It simply became Raft Boat. This was all down to how the engine was being added at the rear. In its early days, this was simply attached between the hull and top section of the main body. Sadly, this did mean that it was possible to pull it off quite easily. So they made a change to it, and now the engine has a section that goes much further inside to be hooked in to the rest. This way, the engine can't be pulled off, unless you put in a lot of effort. This also saw a change to the metal section and this was shortened a little to allow normal wheels to be used. For the 1990s/2000s, the model used a very thin wheel, which was an older wheel that was still being used on occasion. They decided it was time to update it to one of the standard wheels in rotation. Being much thicker, this meant the axle needed to be shorter.
