Four thousand people signed a petition against the plans

They say the island's politicians have failed to listen to the thousands of people who were opposed to the �3.4m project.

The States vote in favour of the new marina has been welcomed by the Guernsey Boatowners' Association, which represents about 1,100 islanders.

The House decided by 32 votes to 20 in favour of the Board of Administration's marina project, following the heavy defeat of a series of amendments.

'Sad day'

The result was swiftly condemned by those behind the campaign to keep St Sampson's Harbour as it is.

Gary Blanchford, of the Save Our Harbour Group, said it was a "sad day" for the island and the 4,000 people who had signed the group's petition.

"St Sampson's is an area of character, and a modern marina, especially one that isn't a visitor marina, will be just another boat park.

"It will take away some of the character of the area, especially in the harbour."

Warmly welcomed

Mr Blanchford said the vote was a clear example of why many people are disillusioned with the States.

However, the decision was warmly welcomed by the Guernsey Boatowners' Association, which has 1,100 members.

Association President David Evans said he was delighted to see the marina plans go through without amendment.

"I am very pleased indeed," he said.

"It will give many people who want smaller boats the opportunity perhaps of having a mooring in the future."
