Ok, what I'm about to say might come off as blasphemy to the accepted notion of how a 6.0 should be rigged, but so be it, here goes...

I believe that the accepted approach to the 6.0 is wrong - that you keep the huge jib and add a large spinnaker. I believe what should be done to this boat is give it a good square top main, alter the jib to sheet to the front crossbeam, and run a flatter more modern kite like that on the Nacra-20. I have yet to try this, but for my experience base on this I have raced my 6.0 with stock sailplan, and with very nice Smyth sails (square top main, even bigger jib). The other 6.0 in our Fleet has used similar sails to the Smyth sails with the NE style spin on a snuffer rig.

The big jib on the 6.0 is nice for reaching, but I think the overlap with the main compromises things upwind, and the wire system is a bear. The tramp loops are a nice way to eliminate this, but I believe that leaves something to be desired as well. Get the jib trim wrong on a big overlapping jib and see how slow you can go on a fast boat..

But if the chute being used is capable of sailing at higher angles like the N-20 spins, the need for the big butt jib goes away and the boat has a better useable range under spinnaker. The more modern shaped flat top main can help recover lost power on close reaches. The only real downside I can see to this is in real light air stuff, but honestly I'm not convinced it will be that much.

If I end up keeping my 6.0 I'll be trying some of these things. Maybe I'll see what happens when the N-20 boards are used as well...

Flame on.
