Chris Gee Windex vanes allow for different tab angles to be set....
The tacking tabs should be set depending on your boats pointing capabilities.
It can vary from 65 to 50º.
On my boat they are set at 50º, but I can point pretty high, so its not a good example.
On the average boat these should be set at 60º for cruisers or 55º for race boats.
Rember they point apparent wind.
My boat does'n have inside genoa sheets because the deck is wide, but due to another reason, somehow related to beam....pointing ability.
My boat is very beamy, therfore it suffers in pointing when comparing to a boat with a narrower beam. My boat was designed to be a good downwind sailer.
Therefore, when designing the deck, and the cabin, we needed to improve its pointing ability, so the tracks locations on the deck were decided based on moideling. Once the track locations were established, we built the cabin width around these limitations. But in my case we even played with mast location, and that made us change keel location and CofG and CofE....
Deciding if a boat should have inside or outside genao sheets really depends on pointing abilities, the gap between main and genoa and other factors sich as momentum, bow design, keel location etc.
Technically if the boat was not designed for it, and you narrow the gap between the genoa and main, you will be able to point higher, yes... but you won't go anywhere because you wont move....
This is because the gap decrease will "deform" camber on the main. These things are all related.
Jim, I am also sorry I didn't read the whole thread. So I might be missing your main question here.
