Ok Who Knows,
The story is you may well find a good second Hand unit if you shop about on these pages. Have a chat with Landyacht but from my side of the fence I would suggest you look closely at Building a LLM (Lake Lefroy Mini) They are fairly simple and the Building becomes a little addictive. You will find that there is any amount of help within these pages (Ask and "They will answer")
I don't know how much you have read here but it would seem that there are a couple or few members over there where the Crows Fly Backwards. Lake Gilles and Gairdiner and the Salt Pans are good venues s well as a few beaches over there. Just watch this place and watch them come out of the woodwork. Best of luck with your decision and get the Family into the Sport.

Have you got a place in mind where you plan to sail, thats a good place to start , or you could end up with a yacht that doesnt suit your needs .
do you have any skills or tools to build one, as thet can be the cheapest option by far
