SashaJ said..hi we are beginning to sail and r looking at the above boat,r these ok for beginners and can they be sailed by one if need be (later) and is there any weight restrictions for two people?

They are designed as a father son type of racing boat so the weight restriction reflects that. I can not remember what it is but it's easy to find. They will carry two adults though if your not fussed about racing in class. The earlier hulls are more forgiving for beginners, it's a development class and the current boats are very narrow on the waterline and may seem unstable.
In NSW the association did have a solo division where they were raced with the main sail only. The mast was shifted forward a few inches. Not sure how long that lasted, in moderate conditions they can be sailed solo with the full rig.
Because they are a development class the resale value is poor. This means you can get a pretty good boat for very little money. I would suggest a full 'glass boat with an alloy mast though. Feel free to post a link of the boats your looking at and we can offer advice. Lot of fun for not much money.
