Ok, take a look at my freinds 6.0NA here. The trick to convertingot self tacking, without loosing sail area isto move the forestay out to the front of the bows. Any old traveler car and track will work on the cross beam to get you there. If your interested in thisI will diagram for you how the sheets are run. Oh you really can't do this without a VTM bow foil, I believe it woulkd cause too much sideways force on the bows. If your 6.0 came with one your god to go. I have seen this boat pass almost every other type of boat on this forum until the downwind leg when the inters and T's pop their shoots.
