    "WMHS gives 470.8×60.9×28.2 ft and describes the rescue of all 45 crew:37 by Samuel Mather and 8 later by Coast Guard helicopter. Its photograph shows two cargo-mast stations forward of the central house and one aft, with a compact funnel behind the bridge. [WMHS](https://wmhs.org/the-nordmeer-goes-aground/)."
