I'm in the process of setting up a spi for my H16 and will try to rig the spi so I can roller reef it. I sail single handed and want to try the spi in low wind conditions.
My question is (I haven't seen my spi, arriving this w/e), is the luff straight enought to be rolled? will/may need modification to do this I might assume. Can the spi be used if the luff is modified to be kept straight and tight (so that it can be rolled)? All the photos I've seen with the H16 spi show a sail with more of a genaker shape - ie a straighter luff seemingly pulled tight.
Bottom line - I want to roll my spi and sail it like a genaker/hooter or whatever. Does anyone with experience with the H16 spi think this is possible?

Thanks to all
