Something else I forgot and it may be nothing, but check the measurement of your bridal tangs from the main beam.

The reason I say this is that when I spoke to Performance they had mentioned the name Roy Seaman a few times pertaining to these boats. In looking at a few of the 6.0 he had brought to the Milt and the other ocean race we do here in Ventura, he was all about huge jibs and radical mast rake. To accommodate the jibs, he had the bridal tangs almost to the front of the bows.

fyi - This may screw you when getting new rigging
