Currently being restored by Nick Finazzo of Pier 500 Marina, Wyandotte, MI. Nick says: "Dryden 4 tugboat hull # 751. I purchased the boat over 3 years ago from a gentleman named Barry Shepard. He purchased it directly from the paper mill. I have been doing an extensive restoration to this tugboat since I purchased it. You can see the attached photos. Just some of the work I did to the tug was reproducing exact replicas of the original metal window frames. The old ones were just too rotted to repair. The tug is fully functional and to the best of my knowledge has all the original parts. The winch is in great working order and as you can see it has been stripped to bare metal and repainted. The entire boat has been sand blasted Inside and out and painted. The paint I have been using is called Por 15, it's an incredibly tough paint."

Nick continues (Dec. 2006): "She will be 100% complete this spring. I don't have much to do to her. I just need to restore and paint the wood flooring in the engine room, install and hook up gauges, restore wood windows , and some other misc details. I have also started to write down some of the details of my restoration. I am hoping that it could be of some use to anyone wishing to restore theirs. I have been very tedious with the restoration and kept her as original as possible, Every nut and bolt was marked during disassemble and put back where it came from. Every square inch was sandblasted and painted with epoxy paint I even got between the keel cooler and hull to protect the metal."
