Diving the wreck

Iona II is a protected wreck and all divers need a licence before visiting the site.

The Iona II was designated and declared a protected wreck in 1989 as it was considered an important part of the UK’s maritime history that was threatened by environmental and human activity. There is a designated area of 50m radius around the wreck within which certain activities are restricted including anchoring, diving, and salvaging.

Anyone wishing to dive the protected wreck Iona II must have a licence from Historic England. There is no cost for the licence and anyone can apply. There are two ways in which licences can be obtained for this wreck:

  1. The Lundy Warden, local charter boats and several local dive clubs have licences to dive the Iona II which will cover any divers visiting the wreck with these organisations. The names and contact details of divers must be given to the charter boat operator or dive club leader to be passed on to Historic England.
  2. Private vessels or dive clubs without a licence will have to apply for a licence to dive the wreck at least 10 days prior to the planned dive. You can find more information on Historic England's website here. 

The site

  • The Iona II is on the east coast of Lundy Island.
  • The seabed around the Iona II wreck is generally flat, with a slight slope east of the amidships area. The seabed is coarse, firm, level mud and fine silt with some areas of fine sand within the wreck and some gravel patches around the boilers.
  • The wreck lies at 22-28m depending upon the state of the tide.
  • Visibility can vary from 0.5m to 15m.
  • The best time to dive is at slack water which is two hours either side of low water.
  • Visibility on this site can vary from 0.5m to 15m but the most typical visibility is 4-5 metres. Factors influencing the visibility onsite include divers disturbing the seabed silt, the algal blooms that are common in April and May and a high degree of suspended sediment from river run off after storms.
