Trail-Craft
In the early 1960’s, in the spring edition of Boating magazine, there was a small ad for the Trail-Craft Corp. boat featuring, sun deck, diving platform, duck blind, tent and trailer with a length of 9’4″, costing $499.50. Engineer/Inventor, Resta Sullivan Gregoire had found a way to pack an immense amount of features into such a small package. He had created a pontoon boat single wheel trailer that could not only handle up to a 10 HP engine, but could also sleep 4. He had attempted quite a few different endeavors one of which was the unsuccessful Trail-Craft. In the info I found about Mr. Gregoire, was an entire history write up of his life. Really great read if you have the time. He led a interesting life and was responsible for some great inventions. Below is family tree article I found about Resta. A great read about the life of a single wheel inventor.
