Here's specs on the Coastal Canaveral.
Twin screw towboat, built 1971 by Main Iron Works, Houma, LA. 54.5 ft x 20 ft. GM 12V-71 diesels, 800 hp. Owned by Coastal Tug & Barge, Inc, Miami, FL.
Peter and windham79, if you have a drawing I can see of the boat you're building I may have something very close to it. I have over 5,000 photos of towboats and barges.
