Many of the wrecks around Lundy are well documented and the nature of their demise is known in detail, however two wrecks, the ‘Iona II’ and the ‘Gull Rock’ wreck are deemed so important that they have been given legal protection under the Protection of Wrecks Act 1973, therefore to dive these wrecks you must have a licence. Since June 2014, a dive trail has been available for Iona II in order to allow divers to participate in protecting our heritage wrecks.
As Lundy is an offshore site, it is not a suitable place for inexperienced divers as it is subject to strong tidal currents. Appropriate safety equipment should be carried by both boats and divers, and divers should always carry a delayed surface marker buoy (SMB) as well as some method of attracting attention, such as an extendable flag or whistle, in case they surface away from their boat. Divers operating around Lundy do so at their own risk and should be aware that the nearest recompression facilities are at Plymouth.
