Neill, suggest that you wait until the next tropical low comes this way. I have sailed both lake Samsonvale and Wivenhoe many times in my skiff years ago. 4kts on Samsonvale NE - SE equates to about 20 - 25 on the bay and worse at Wivenhoe and Somerset. You will probably find that you will need permits and Public Liabilty Cover. Westerly Winds like this morning could be fun though....watch out for tree stumps, old barbed wire fences,and old tractors hiding just under the surface. Other things to watch for are weed patches like carpet (leads to serious face plants) and D.P.I. Fisheries Research Electricuting fish and any stray Kiters.
