There are not many sources on the Viking and Native American interactions in North America. Both archaeological and textual sources are few in number and many of those sources are rather questionable in themselves. To my knowledge, there are not currently any finds that would suggest that the Native Americans did try to create sea faring ships after their interactions with the Vikings.

If you are interested, there is more discussion of textual and archaeological sources on this post that goes more in depth. The focus is more on the saga sources, Viking settlement, and their interactions with the native peoples.
