[quote=TylerH]Will,
Standard I-17 is either the sloop rigged Aus I-17 (lighter as well) or the EU I-17 that is a pure singlehander. Than you have the I-17R that is popular in USA with a much taller mast and much larger mainsail area and that is nearly exclusively sailed singlehanded although a jib kit is available for it. All have 17 sq.mtr. spis. The F17 is the US I-17 platform with the R-rig but with a larger spinnaker sail. The name suggests a Formula class setup but from what is available as class rules it appears to be a single manufacturer one-desig class with a F-name. In Europe The Texel rating system also recognizes the I-17XL (not the same as I-17R) and I-17 standard with jib (not the same as Aus I-17 as that one is lighter in overall weight.
I-17R/F17 seems to be popular around the great lakes. Sails fast in light airs but is rumoured to loose "some" when the winds increases. This also refers to the ease of sailing. At least that is what I was told by some I-17 Sailors. Also there is an ongoing debate on its overall weight hence the fact that it is not advertised. The US version should be lighter than the EU versions as measured by Texel though. But still heavier then the Aus versions.
In Asia several Aus I-17's (sloops + spi) race Taipan F16's. Great fun, but some bitching is going on about ratings. The F16's sailors seem very happy to go head to head with them, probably because they feel that they have an edge.
Anyways the Aus I-17 is about 125 kg ready to sail sloop + spi.
I seem to rememeber it had asome 13.9 sq. mtr. main a 4.25 mtr jib and a 17 sq. mtr. spi
The EU and US versions are heavier by at least 15 kg's, sometimes by 30 kg's depending on which source you believe.
Both the EU and Aus version use 8.5 mtr mast while the US version has a 9.1 mtr mast that is made of carbon fibre.
Mainsail area on the US version is 16.44 sq.mtr.
Hope this helps.[/quote]
