I'm looking for a used 150 furling genoa for an E32-200. Reported I and J dimensions for the boat are 42' and 13.8. Dimensions of the used sail I'm interested in (which is a long distance from here) are I 39'6" and J 21'4". What additional information do I need to get to figure out whether this sail would work for this boat, as a 150 genoa should? Thanks for any help you can give on this.
