They have been casting off their inhibitions, dodging midges and defying Scotland’s capricious climate for half a century.
Now the country’s largest naturist organisation is to celebrate its 50th birthday by launching a naked cruise down the Forth.
Around 80 hardy nudists will sail under the Forth Rail Bridge next month as part of a maritime celebration of the clothes-free lifestyle.
The three-hour boat journey, which will feature a barbecue and live music, is the most northerly of a series of UK-wide events being organised by British Naturism, which was founded in 1964.
The body’s Scottish spokeswoman Juliette Tavendale hopes the cruise, which will take place on Saturday, July 5, will attract new faces and help bring nudism into the mainstream.
She said: “We are keeping our fingers crossed for blue skies and warm weather but the main thing is to have fun and celebrate 50 years of naturism in Scotland. We want to show that it is alive and well and does happen here.
“We will be naked after we leave Hawes Pier in South Queensferry and the boat will have plenty of room both indoors and out.”
“The cruise is open to all, and people who haven’t tried naturism before will be made very welcome.”
Ms Tavendale is particularly keen to welcome more female recruits and feels saturation coverage of toned celebrities has left many women feeling too worried to disrobe around others.
“We would love to attract more women and our message is: ‘It doesn’t matter what you look like. You are beautiful just as you are.’”
The Forth Belle has been used for jazz and disco trips but this is the first time it has been used to host a naked cruise.
A spokeswoman for Forth Boat Tours, said it was a private booking and declined to comment further.
