SO? The suggestion remains the same, if you go to a sailmaker you will get a perfect sail made for your boat and your normal sailing conditions instead of a generically designed sail made for average conditions worldwide. Don't get me wrong, Hobie hires a pretty good sailmaker and the sails are well made; but he/she uses software to make the foils. Decisions the sailmaker makes include amount of camber to design into a specific sail. Worldwide, the average beach condition is typically 8-12 kts; if you sail in 8-12 kts predominantly, hobie sails will work very well for you. If, however, you sail in lighter breeze or heavy breeze...you could do better. Of course, if you don't care and just want a "hobie" everything....that's OK by me; seems most people who own hobies are wedded to the brand, and like I said, they make a good generic product. Since I come from a bigger boat with no established one design sailmaker, I'm used to shopping for sailmakers (until I started making my own).
asymspin/gennaker design for boats also depend on the AWA you prefer to sail as well as how much apparent wind your boat develops in your normal winds. It is quite a large selection. Here's an example from North Sails (and how they entice big boat owners into buying LOTS of sails). You will need the latest Acrobat Reader to read this thing...
http://www.voiles-alternatives.com/docu ... _v3_en.pdfIf you want an answer to your original question, you gotta know the luff, foot and leach length of your spinnaker and compare that with the luff, foot and leach length of the T2 gennaker. You have some leeway, though. You probably have some line between the sprit and the tack as well as extra halyard above the head. Also, you can add another eyestrap on your spin pole closer to the bow if the gennaker's luff is shorter, or add another hound on the mast, and/or move the turning block sheeting location. You can make nearly anything fit and work. Heck, with the right top down furling system, you can furl your existing spinnaker with no modifications; or you can have a sailmaker add an antitorque line into the luff of your spinnaker and use a bottom up furler. All sorts of possibilities.
