Last month’s final round of the Honda Formula Four-Stroke Powerboat Grand Prix, held in Douglas Bay, will feature in Blue Peter's 50th anniversary programme tomorrow.
The popular children's show is due to be aired at teatime on BBC1.
It will include presenters going head-to-head in their own powerboat race before joining three teams in the 150 horse-power class.
