hamilton has also experimented with the foilboard, an innovative surfboard which incorporates hydrofoil technology allowing a higher degree of precision and effectiveness of aerial techniques within the water. he has become a proponent of stand up paddle surfing, an ancient hawaiian technique that requires a longboard and a long-handled paddle, as well as considerable skill, strength and agility. purist surfers have blasted him for this, but hamilton calls it a return to the traditional hawaiian way of surfing, as practiced by king kamehameha i and his queen kaahumanu almost three hundred years ago.
