Thanks Dave and Mary for the info. I guess I will keep the old square rudders till i come across some new ones for a reasonable price. Buying the MX main, jib, new paint, and tramp kind of hurt the budget this year. I still feel that a centerboard boat is superior (durrablity wise) to the long daggerboard boats like the NA6.0 and the Inter 20's. I just cant imagine ripping out a dagger board box because you were sailing in unfamiliar water....
