Nantucket Island lies just south of Cape Cod. The area is quite shallow with lots of shoals like the The Great round, Tuckernuck & Old Man, and navigation channels like the Great Round Shoal to the east. This makes for a very interesting 3D chart. The Island has a very distinctive shape with many “ponds” like Hummock, Miacomet and the very unusual breakwater / barrier beach Coatue which creates the natural harbour of Nantucket. Framed in our black/charcoal frame, it works very well with the NOAA chart colours. Add surround lighting and you have something truly special.
