On the web log page entitled Shipwrecks for 7/25 is an article on the current condition of the Andrea Doria. The link for this site is
http://shipwreck.blogs.com . This corporation has over 120 dives to the wrecksite, has contributed to over 20 television documentaries on the Doria, four Doria books and owns three museum exhibits loaded with items from the Andrea Doria (the largest collection of Andrea Doria items in the world). The parent corporation's website can be found at
www.nauticalresearch.com and has plenty of underwater and land-based pictures of the Andrea Doria. Additional information on the Andrea Doria can be found at their survivor's webpage at
www.andreadoria.org and it does contain full deck plans of the ship. Best of luck with your diving - but be safe! The Doria cuts you a lot of slack---just enough to hang you with!
