this is in port sorell-or shearwater (tas) my home spot for both the speed and other pics...... it's around a 20min drive from devonport.the speed runs over 650m long on low tide and the wave ones are on a high tide.but the waves happen when is easterly winds and the speed run best from sw to nw winds.my dad and dave have don over 41 knots with other hovering around 35 up.
the line on this map is the speed run following the sand bar showing the run to get on to it to.
