Repairs to a Cornish harbour costing more than a £1m have been put off until the autumn.
The quaint fishing village is a very popular with tourists
Work on rebuilding part of the wall of the inner harbour at Padstow should have started last month.
But plans had to be redrawn after test drillings showed deeper-than-expected mud near the foundations.
It is hoped the project by Padstow Harbour Commissioners and the Environment Agency, will be finished by the start of next year's summer season.
Local people are disappointed by the delay, because the condition of the harbour can affect tourism.
Padstow boat owner, Peter Reveley, told BBC News: "It's 100% important because it supports the car park and tourist building and is a big mooring place for yachts. If the wall goes, everything goes."
