27 meters is about 81 feet. That's a big wave.

There is an IMAX movie filmed in (IIRC) 1998 off the North Shore of Oahu where some guys were surfing waves nearly that size.

Go here for pictures of the largest waves surfed in the past few years. Most of these were Jet Ski Assisted not paddle in waves.
