Get involved Dive Trails A1 Submarine Dive Trail In 2013 the Nautical Archaeology Society with funding from English Heritage (now Historic England) established a diver visitor trail on the protected wreck of the HMS m/A1 submarine that sunk in in the eastern Solent in 1911. The aim of the project was to develop a visitor diver trail on the designated wreck of the HMS/m A1 submarine (designated under the Protection of Wrecks Act (1973) in 1998 (Statutory Instrument number 1998/2708), with an amendment in 2004 (Statutory Instrument number 2004/2395). The dive trail is organised and managed by the NAS in partnership with the Southsea branch of the British Sub-Aqua Club (SSAC). An underwater information guide for divers visiting the site was designed that will aid navigation and assist visitors in recognising features on the wreck. This guide will also explain the background to the remains and the issues of protecting and managing the wreck. An online interactive visualisation was created and supporting webpages will be hosted by the NAS and SSAC where descriptions and photographs from visiting divers can be posted. The trail will be promoted by press release, circulated to several major diving magazines, and promotional materials for local and major diving shops. Visualisation Diver visitor trails have to date proved a useful way of managing public access to wrecks protected under the Protection of Wrecks Act (1973). The goal of any diver visitor trail will be to improve public access to the underwater cultural heritage whilst not putting that heritage at risk of damage as a result of increased access. This project is aiming to emulate successful trails established on the other protected wrecks of HMS Hazardous in Brackelsham Bay, West Sussex, on HMS Colossus off the Isles of Scilly, on the Coronation wreck off Plymouth, Devon and on the Norman’s Bay Wreck off Eastbourne in Sussex. The wreck of HMS/m A1 submarine was identified as a suitable candidate for a visitor diver trail as it is well documented, historically interesting to divers, substantial and upstanding which will make it easier to locate by visiting groups, because it is robust enough to withstand improved visitor access and finally because it is lies in a geographical position where visiting the wreck is relatively simple and safe. Designing the trail involved collation of all the background information needed to design the underwater guides and the promotional materials.
