Notice how the tension members on the A frames are treated.  These two wire systems each have have roughly double the forestay load on each of them.  Stainless does not like to be cold-worked.  A thick continuous wire making a sharp turn is a classic failure mode.  It is less costly.  I am a bitch about details like this.  Mine cost more to do, but are more reliable.  This is a mission critical part of the catamaran.

Now the cheaper way.  And look how planning for the furler down low helps.  Get it done right.
