Bob:
I have searched for just such a book myself, and not yet found it. I have many other reference books, such as already have been mentioned above, but not found anything that specifically covers dugouts from the Americas or Africa, other than the Pacific northwest, and Haddon/Hornell for Oceania. A friend tells me there is a French text similar to H&H called "Pirogues Oceaniennes", by Jean Neyret. This is a two-volume encyclopedia of just about every indigenous watercraft from India to Hawaii + a few from north America (i.e. couple of kayaks and canoes) + South America + Africa. The Dutch, being great explorers a few hundred years back, may also be another historical source, and it wouldn't surprise me to learn there is something similar to be found in Germany. Having the Internet as a search tool has been a real blessing. Occasionally one comes across a link to a museum, a collection or even travel posters which show indigenous watercraft. I have used these and other sources to assist in learning more in relation to my own world-wide model collection.
BTW, one of the best little booklets I have ever come across on dugouts from N. America is "Canoes and Kayaks of Western America", by Bill Durham. It was OOP for a long time but was re-printed a few years back by Copper Canoe Press, of Seattle. More historic info and drawing details than anything else I've ever seen. And, for details on the various styles of Alaskan kayaks, you can't beat David Zimmerly's "Qayaq", by U. of Alaska Press.
If you find anything that covers the international scene, please let me know.
Good luck searching.
