The latest suggestion of what Prince William is to get up to on his stag do is that he'll be embracing the most extreme of watersport activities, at least according to The Sun.
His brother Harry has been placed in charge of organising William's last night of freedom before he marries Kate Middleton in April and there has been much speculation as to what he will get up to.
From a trip to Africa, to a lesbian burlesque act, Prince William has been linked with it all, but the frontrunner now is that he and 20 mates will enjoy a day of off-shore danger, which will include racing speedboats and water-skiing.
According to The Sun, Harry, 26, held secret talks with one of Britain's top watersports firms on the south coast, although it doesn't appear to be all that 'secret' now.
The party will then continue into the night at local bars and a friend's house, although it had been tipped that privacy will be ensured with a party taking place at Clarence House in London.
A Clarence House spokesman said: "The stag party is an entirely private matter."
But a bit speculation will do no harm.
