Must be a poor surf day if you are browsing my web page! In fact I am still trying to put theory into practice 31 years after my engineering thesis. Swapped to a Mal last year and am still getting used to the extra inertia (good for catching em but harder to turn). Steve O'Donnell (Harbord Rd Brookv...

They might be caused by asteroids impacting the Tasman Sea or underwater landslides on the edge of the continental shelf. Our crowded coastlines seem to be particularly vulner...
