James King, The Three Voyages of Captain Cook Round the World…
“ Whenever, from stormy weather, or any extraordinary swell at sea, the impetuosity of the surf is increased to its utmost height, they choose that time for this amusement, which is performed in the following manner: twenty or thirty of the natives, taking each a long narrow board, rounded at the ends, set out together from the shore. The first wave they meet, they plunge under, and suffering it to roll over them, rise again beyond it, and make the best of their way, by swimming, out into the sea. ”
