Before tow-in surfing was created, surfers weren't capable of catching waves that were between tall on their surfboards made for larger waves called “guns”. The biggest wave one could catch before tow-in surfing was in the range. Tow-in surfing is accomplished by taking a personal water craft (PWC) and a tow-rope and combining that with a surfer. One person pulls the surfer out to the break on the PWC. When the waves comes, the person on the PWC tows the surfer via the tow-rope into the wave. Once the surfer is in the wave, the rope is dropped. The surfer is then on their own to surf some of the biggest waves in the world.
