G'day BRIAN.
We actually do just that, ie make available to anyone who wants to put their own boat together, evey part of the cat from the hulls up. We have always sold cats that way, ever since the 1970's, but when our end product has been finished straight off the factory floor in full race tune and trim, we have never had a lot of takers. It seems that when push comes to shove most people like to buy the cat ready to race and not have to put in the hours chasing parts. Most times potentual customers have found that by the time they go out and pay full retail prices for fittings, sails, sheet lines, etc, they can't save themselves any money from what we supply ex factory (we do have a much better buying price from the suppliers than "retail"), and our fit out time is only a fraction of what it takes some one to fit out a cat themselves when they are doing it as a one off.
