| On October 26, 1973, the Nantucket lightship reported sustained winds of 115 knots, and seas of 45 feet. |
| The first lightship, established in 1732 at Nore Sand in the Thames estuary, was rapidly followed by others. |
| The lightship has had uplighters added to its fore and aft masts with lighting units added around its deck and jetty. |
| Like the lightship, the wreck rests in around 34m of water so it's another deep, dark dive. |
| Ambrose, built in 1952-53, is the only lightship equipped with a modern catoptric type lens. |
| A computerized model was produced and an inclining experiment was carried out to establish the vessel's lightship characteristics. |
