mhdishere,
Although I am heavily influenced by the area you are referring to in New York, my layout is based on the operations of the B&O around Baltimore harbor. I have often been tempted to model the area in Staten Island {around the St. George Ferry Terminal}, which would allow me to get some CRNJ equipment, but have kept it around my home town's harbor area. The B&O used carfloats pretty extensively at one time in the Baltimore harbor area, shuttling cars from Locust Point to the canton area. The Walthers tugboat is not really correct for my layout as the B&O had their own tugs at one time, and then used the Curtis Bay towing company,which Moran later bought. I chose to loosely model the modern day Moran paint scheme as they currently look at the city pier in Fell's Point, MD. Have a great day.
