The pictures of the paddlewheel grass clipping boats reminded me of this one. When my Dad, white shirt and dark pants in the picture, retired he started a small fabrication company where he designed and built several like the one pictured below. It was used for clearing fallen trees and doing other work on the waterways. It has several attachments for the hydraulic boom; an excavator bucket and clamshell, a small cutterhead dredge, hydraulic wood saw to trim branches or cut trees, it had a JD diesel driving the hydraulic system which powered the paddle wheels, other functions and attachments. Steering was by stopping or reversing on or the other paddlewheel. The operator sat in a nice air conditioned cab built by John Deere for their grain combines. The boat fit on a custom built trailer for transport and launching. Shown on Bayou Lafourche in Louisiana about 1995.
