Good morning Jonathan.
That plating certainly looks impressive. Up until now I've always used strips of cardboard. Why didn't I ever think of metal tape? In the words of my hero, Homer Simpson, "Duh". I was worried about tape or plates lifting but I can see no evidence of that in your photos. A nice job.
I've found a recent picture of the tugboat that bears a resemblance to mine, here's the address if you're interested
It shows the plating quite clearly. It's in and out riveted.
Best wishes Tim
