As an alternative. Buy an old high clearance tractor, fit an extended draw bar & charge to launch boats off the beach. Proceeds to fund for new jetty. Watch the council line up with their hand out to collect fees etc. With enough usage would show the pollies just what the need is. If I was still boating would use it as would open up the southern end of the bay without the long run to & from Rosslyn Bay. That corner is quite protected from most weather. Launching out past the rocks could be a bit dicey in anything but calm weather in my opinion. Would not like to see the jetty go too far beyond the rocks as that could alter the northward flow of sand along the beaches.
