Rope/Line Size

Well, the time has come to replace the running rigging on catboat. Does anyone know the lengths and dia. of the lines one the Horizon Cat. I am replacing them all. Any help would be greatly appreciated!!

I ordered 46 feet of T-900 double braided 5/16 line for the throat halyard on my horizon cat.  That was playing it close because I decided to splice the eye myself.  Unless you know how to do it and have the tools, order your line with a pre-spliced eye and 46 feet will do.
