GI Joe Adventure Team Sea Sled 1970s

Picked this up at one of my vintage fleas in a box full of GI Joe stuff. The shark was also in the box and may have originally come with the sea sled. I know the shark came in a set with an orange wetsuit but it probably came in other sets also. The Adventure Team happened after Hasbro shifted away from the military sets. So the foes of the Adventure Team were small animals such as this shark. But this piece fits any era of GI Joe.
There is also an orange version with a cave which I don't have but will someday.
