Sorry I couldn't find the discussion on dinghys, so I'll start another.
Lake Macquarie Yacht Club is selling its fleet of Sabot dinghys for about $300 each. I think there are about 9 available. They are small one sail dinghys with a guyed mast. The Dinghy itself has a forward section with a lot of flotation. All you would need to do is to add rowlocks to row or better still just use it to sail up to the boat. No fuel, no greenhouse gasses, wow!
If you've got kids what better way to keep them entertained when you're sitting on the mooring.
Just an idea,
Greg.
