$250 is a gestimate based on the retail cost of new inter 20 daggerboards at $495 each. I do not believe that this is a realistic cost and know that I can make them for significantly less. I do not know how much 5.5 boards are retail and I have not built one yet so I do not know how much time is involved I am willing to negotiate the price and it will be much less than performance because I am building them myself and they will not be race sanctified.
