IOMICA Forum

I am about to build the A rig for my Triple Crown and I am wondering what material to use for shrouds and stays. I am looking at single strand stainless steel wire but I heard somewhere it creates radio interference. Any advice welcome, thanks.

Thanks for the answers. Since I molded the fin box over the fin, increasing the fin thickness is no longer an option. I'll call my first IOM a light airs boat and build myself a moderate to stiff winds boat next time. So it's not a bug, it's a feature.

Maybe a different twist on the same topic - pun intended - I built a fin and I have about 3 cm of flex or curvature if I hold the fin horizontal from the box end with the 2.4kg ballast attached. Is there any performance issue or impact directly linked with fin flex? How much flex is tolerable?
