When I was thinking early on about fitting a kite to the cat I wondered why a catamaran would need a spi pole at all particularly my 430 given that the mast at 50% of hull length. This puts a sail rigged at the bows a generous distance in front of the mast. I wondered if I set the sail from a guy rigged between the hulls, I would have a spi of sufficient and usable dimensions. The other thought I had was, if rigged this way, it would be possible to have the tack adjustable athwartships which I thought may be of some advantage. I reasonably thought [in my mind] that the further to windward the luff was set, within reason, the better the boat would point. I'm not exactly sure why I felt this would be the case, but I did. Logos?

Well it remains a thought as I went the traditional way.

I think it'd be worth trying but I ain't gunna do it cause I've just about had enough of spi development for the moment.
