With reference to the Maudslay Shipbuilding Yard at Greenwich. I am currently living and working in the city of Salvador, Bahia, Brasil. As a scuba diver I am taking advantage of the local warm water and diving as often as possible. One of the sites we visit, especially if we have new divers, is a wreck know locally as the Black Drr, a Norwegian steam/sail ship. Very recently a local diver has discovered that the ship is actually the Blackadder. She lies alongside the shore line at the bottom of a rock outcrop. Two of the masts lie pointing out to sea and there is very little of her hull left. The site is between 2 and 10 Metres and approximately 50 Metres off shore.
