What about a reef off Swanage?

The Environment Agency (EA) has supported the first phase of a scheme to
obtain permission to sink a ship that can be used as an artificial reef for
divers at Ringstead. ‘The lack of premiere diving venues in the South West
was a key finding of the recent Enjoying Water strategy, led by the EA.
They are keen to encourage more people to use the coast and inland water
for recreation in a sustainable manner.  The first phase of the Wreck to
Reef will concentrate on commissioning independent experts to produce a
series of surveys necessary to progress the project in a sustainable way.
The EA has contributed £8,000 towards a marine survey of the proposed site,
an Environmental Impact Assessment (EIA) of sinking a vessel and a
comprehensive business plan.
