It does look like a novi with the nearly plumb stem and sharp forefoot. I remember seeing that boat when I was a kid. For another Plymouth boat, I wonder if any Jesse Craft are still around. These were built at their yard near Cortage Park.
I know of two. one is in Gloucester ands one is in Newburyport in the summer. both are 40fts. nice boats. I think paul and bruce heberts father had a certified jesse4 out of green harbor years ago. nice little passenger- tuna boat
Henry Kunkle is a blast from the past. He owned and operated a great sea food restaurant here in Halifax." Lobsters Etcetera" this was in the 80's. If I remember right, he winter stored that boat next to the restaurant.
