Trapeze ropes

If you look at any class where rope trapeze wires is not barred in the class rules it can be seen that the rope is the overwhelming. I have not seen  49er sailor using wire trapeze lines and an entire fleet of future olympic champions cannot be wrong. Steels density is around 7800kg/m3 whereas rope is just than water at 1000kg/m3 as it floats. Therefore although the rope is slightly larger than an equivalent wire then it can be seen it will be significantly less weight. I am not sure that you would be able to measure the difference in drag between a 2mm wire and 2.5mm rope trapeze line even in the wind tunnel.
