“Marmoler” is a wreck lying in 42 metres of water off the bay of Montgo. The wreck dates back to 17th May 1971 when the Italian registered Avvenire ran into problems during a storm and sank with its cargo of marble on board - hence the popular name “marmoler” - but luckily the crew of 8 managed to escape.
The wreck sits upright at the bottom in 42-45 metres and is therefore only suitable for experienced divers. It remains largely intact, including the bridge, which rises to 30 metres and vast slabs of marble are that are still on board, visible in the hold due to the lack of deck.
Avvenire was built in Holland in 1930 and is 47.25 meters long and of 8.34 meters wide.
Local dive centres organise dives to the marmoler, but if you want to go independently the GPS co-ordinates I have for it are: 42°N 06′48″ 03°E11′85″ - I don’t know how accurate those figures are though.
The dive profile above is from 13th August 2005. There is a lot of red on the ascent thanks to my computer thinking I didn’t have enough air - it reckoned I had 6 minutes of air for a 12 minute deco stop but in fact there was spare air at 5 metres that I didn’t use.
Also note that on the ascent we stopped for a minute each at 20 metres, 15 metres and 12 metres. According to DAN, making short deep stops reduces the likelihood of suffering decompression sickness by a factor of 10 and while it extends the final stop at 5 metres it is something I like to practice.
Time on the wreck was relatively short at 15 minutes but we had enough time for an explore. Also, we ascended on a buoy rather than the dive boat’s anchor line, which makes it less straightforward as you need to be far more aware of your depth at all times.
