A SHUTTLE boat service from Hayle to St Ives has been approved to start a trial in the summer season.
From Easter, the so-called harbour taxi will carry up to 16 passengers between North Quay and St Ives Harbour.
The rib will rely on the right weather and sea conditions to run the 25-minute service.
St Ives Rib Rides, owned by John Johnson and son Adam, is providing the boat trips, supported by Hayle Harbour Authority and the MP for Hayle, George Eustice.
Mr Johnson said: "I am really looking forward to this new and exciting venture which I hope will be excellent for Hayle."
He admitted the scheme was a bit "trial and error" with ticket prices not yet confirmed.
Passengers will be able to check a website to see what time trips are available, and purchase single or return tickets.
Talks have taken place with holiday parks in Hayle to encourage their guests to make use of the 'park-and-float' to help ease congestion in the summer season.
Megan Palmer, from Riviere Sands Holiday Park, said: "Most people don't like parking in St Ives, it costs too much money. The train is really popular from St Erth, but this would give customers another option."
Mr Johnson said a back-up bus will run when weather conditions prevent travel by boat.
He added: "It will certainly help reduce traffic congestion and ease the pressure on parking in St Ives, hopefully boost trade with local shops and be a pleasurable scenic trip."
Mr Eustice said: "Between them, Hayle and St Ives have a lot to offer and a sea link for the two towns would be a fantastic resource, benefiting tourists and local businesses alike."
Hayle town councillors and chamber of commerce have expressed support for the scheme.
Councillor John Coombe said: "It's a wonderful idea. I am definitely in support of it."
