Van Zandt Pier in Cape Ann is a shore-accessible site featuring a shallow artificial reef. Divers can explore depths ranging from 2 to 7 metres, with an average depth of 5 metres. The site is suitable for beginners due to the mild currents and shallow profile. Visibility typically fluctuates between 2 and 7 metres depending on local conditions. Because the area experiences active boat traffic, divers must use a surface marker buoy at all times and remain vigilant when surfacing near the entry point. Species recorded around this area include wrasses, sea bass, various crabs, and star coral.
