Re: Welded aluminum boats
this is what I got from google. not sure if it is correct:
Earliest aluminum boat builder? [Archive] - The WoodenBoat Forum
"In the latter part of 1945, Bill and Chick Ward created the first welded seam aluminum jon boat. This first Ward Brothers aluminum boat was patterned similar to the flat bottom cypress wood boat of that period. However, the Wards saw the advantage of more rake at the bow and more flair on the sides. After testing this aluminum Jon boat, they realized it was much easier to paddle -- and, more responsive with a outboard motor. Also, they found it much easier to load, unload, and pull up the banks of the river. The name Dura Craft was decided upon; and, an industry was born."

There appears to be controversy over the first aluminum boat. Here are 2 views:
"...the first aluminum boat, a 17’ launch named Zephyr, was built in Switzerland way back in 1890. It was not until 1931, however, that aluminum alloys were developed that were sufficiently resistant to salt water corrosion."

-OR-
"Alfred Nobel commissioned the first aluminum boat ever built (12 x 1.8 m), with a capacity of 25 to 30 passengers. The boat, "Mignon," made its maiden voyage on Lake Zurich in 1891. "
