John Fitch Durham Boat Hull

Hello all.

I am currently drawing up plans for a 22'x5' steam launch based on John Fitch's first steamboat (the first in the United States).

The Indian Paddle method of propulsion can be seen working in two places:

Some of the folks at the Steamboating Forum recommended I come over here for the hull itself.

Drawings of the original boat are typically unreliable, however, it is historically likely that the hull used would have been a shortened version of a Durham Boat.

Durham boats were the predominant commercial vessel in the Delaware area (variations were used in other areas); they had flat bottoms, vertical sides, and were typically 60' long (figures vary from source). They drew only 8" fully loaded with pig iron, and were poled along (rowed in deeper waters).

That being said, according to several sources, there are no drawings left if there ever were any (I have been unable to locate any).

Going off poorly-zoomed pictures of replicas and vague descriptions, I have recreated what I think to be the general hull design for strip-plank construction by a boat shop (I made another version for plywood in case I built the hull myself, but I think I would much prefer to have the hull built to be not only structurally sound [as I could do it], but also aesthetically pleasing, which I think means strip-planking by a real boat builder. I am already building the steam plant and the propulsion mechanism; I don't mind not building the hull itself).

Thoughts?
