Revised plans have been submitted for a new seafront ferry terminal linking the 37 miles between the UK mainland to the Isles of Scilly.
The proposals for a new terminal at South Quay in Penzance follow earlier plans which were rejected in December.
In new plans, a passenger building has been moved, a canopy has been dropped and there will be granite cladding.
Views are being sought before Cornwall Council's Strategic Planning Committee makes a decision on 8 March.
Plans were first put forward in 2009 because the two vessels currently linking the islands, the Scillonian ferry and freighter Gry Maritha, need replacing.
Cornwall Council officers proposed a larger, single ferry, which would require a new larger terminal at South Quay to support it.
Councillors refused planning permission for the terminal after critics said it would spoil the area.
Graeme Hicks, Cornwall Council member for transport, warned that if there was no agreement on the latest Penzance plans, the council would consider a terminal at Falmouth instead.
"We have reached a crucial point and now is the time for everyone involved to work together to deliver this scheme."
John Maggs of Friends of Penzance Harbour, which opposed the original application, said despite the changes it was still against the South Quay terminal.
He said that an out-of-town terminal at Long Rock would give a much-needed economic boost to that area.
"Putting a freight terminal in the middle of the seafront will compromise the possibilities for that," he said.
"It will also lock heavy traffic into the area when we should be looking at opening up spaces for pedestrians."
But Mike Waters, from the Real Friends of Penzance Harbour, said putting the terminal at South Quay would be an economic boost to the town.
He added that opponents of the scheme did "not reflect the feeling of the majority of people in Penzance".
