TOURISM Swansea Bay is the latest organisation to come out in support of the £850 million tidal lagoon project.
Officials are taking the response from members as a unanimous backing for a scheme, which could provide power for 120,000 homes for 120 years.
Its 350 members were asked for their views and business development manager Cathy Lewis said there were no dissenters.
"There was no negative feedback," she said. "We did a group email and there was quite a positive turnout. There were 35 to 40 replies, which was not a bad response. They were in favour of it.
"We regarded no news as good news. If there is anything people are worried about they will come screaming at you."
She said two committee members did raise concerns with officials from Tidal Lagoon Swansea Bay, which is behind the scheme, but they were reassured.
"There was concern about the sewage pipe in the middle and its effect on water quality and about whether other operators can work alongside the tidal lagoon company," said Mrs Lewis. But lines of communication will be kept open.
"It is an on-going process," she said. "There will be other meetings in June and July."
The project has also recently been backed in public by Swansea East MP Sian James, former council leader Chris Holley and Wales rugby captain Paul Thorburn, now a business development consultant, and Swansea Bay Business Club.
Swansea West MP Geraint Davies has claimed, though, that the lagoon would harm tourism and the views of the bay.
The scheme centres on a six-mile, U-shaped seawall from Swansea docks to near Swansea University's new Fabian Way campus.
