Given these rising costs, most of which were met from its own funds, the Trust needed to develop a strategy for the future, and in 2004 commissioned a comprehensive Mullion Harbour Study. This report included seabed surveys, an analysis of 20 years of wave data, and an inspection of the harbour by divers and bore holes, and geological, environmental, economic and archaeological surveys.
Agreeing a way forward
The Mullion Harbour Study revealed that the 100 year old harbour was in relatively good shape, but concluded that sea levels would continue to rise, wave heights would increase and freak storms might become annual events by 2100.
A stakeholder group of residents, fisheries and harbour associations, tourism and environmental agencies, and local authorities, was set up to discuss the Study and agree a way forward. It recommended that the National Trust should repair and maintain the harbour into the future, but it also recognised that if severe storms continued to inflict damage, and as the structure got older, a tipping point might be reached when it would be necessary to call a halt to repairs.
At this point, with the involvement of local authorities and English Heritage, repairs would not be undertaken but the harbour walls might be consolidated to preserve most of the structure for as long as possible.
Following the report, the Trust carried our extensive work to strengthen the breakwaters in 2006, and since then has continued to undertake repairs and maintenance. It is thanks to this work that the harbour survived the 2014 storms when other harbours suffered extensive damage.
