A total of 35 groups from all over the world have already signed up to this years Falmouth Sea Shanty Festival - exceeding last years number.
And a new three-day classics sailing regatta will form part of the event for the first time.
The festival runs from June 14 to 16 and has become a firm part of the town's calendar of events.
This will be the tenth year it has taken place, and so far it has raised more than £25,000 for charity.
It attracts thousands of visitors and singers come from Germany, Holland, France and from Norway to join local groups in venues across the town.
For the last 20 years Falmouth Classics regatta has been a single race held as part of Falmouth Week in August, with around 150 boats taking part.
But a group of volunteer sailing enthusiasts is launching a new classics with races over three nights.
It means that alongside the evening racing, spectators can listen to the shanties being sung both on land and on the water.
The Royal Cornwall Yacht Club's events company is working with other agencies and sponsors on the event.
It will be open to a wide range of classic boats, both sailing and powered.
Chairman Roger Hollingsworth said: "For too long Falmouth classics has hidden its light under a bushel. Making the regatta into a high quality, stand alone sailing event is exactly the right thing for Falmouth Classics, its the right thing for the Shanty Festival and it's going to be great for Falmouth.
"To host a long weekend of great classic boat sailing in the glorious waters of the Fal Estuary, one of the best sailing grounds in Europe, will be a real coup."
Shanty festival chairman and town manager Richard Gates, said: "Linking them makes perfect sense, bringing events on the water and ashore even closer."
Money raised will be given to the RNLI.
