The 198 ft Challenge, built in 1853, was a very early propeller driven vessel. It has two single expansion steam engines mounted on wood bases. It sank in its first year of service June 1853 when it caught fire after its boiler exploded off Cheboygan, MI. You can see in the model where the drum of the boiler is gone exposing the internal fire tubes. The Challenge was discovered this year 2021 by Mark Gammage and Joe Van Wagnen. The model was photographed by Andrew Goodman and Ken Merryman using DPV’s and was created from 2,723 - 30 Megapixel RAW images converted to .jpg for color correction and processing.
