The South Rivers are NOT the problem that some suggest. The 'problems' of the South tend to be those navigating them.
During the week several Hunters sailing boats visited Oulton Broad, these boats sailed all the way from Ludham, without engines, braving the so called problems of the South, and they arrived safely, despite the so called problems. Use the tides and the winds as a friend, not an enemy, simple.
Those short mooring posts at Potter are short for a reason, they are stronger that way. There is less leverage should people tie their ropes to the top of them, less chance of them breaking, simple.
