New York from the Harbor Showing the Battery and Castle Garden

The painting depicts a harbor scene. A boat with a tall sail is on the water, to the left. The boat appears to have a flat bottom and pointed bow. There are wooden poles extending from the water, likely a dock or pier, to the left. A large ship, possibly with three masts, is behind the boat, mostly obscured. The shore in the background has buildings and appears to have a fort or castle-like structure on the right, with a shorter structure on the right side of that. The water is choppy with white waves. The sky is cloudy and blue.
