Jib Sheet Replacement

I'm replacing my jib sheets and in the C 36 owner's manual on the rigging page it calls for 7/16' line at 45' for "jibs" and 55' for "genoas".

Can anyone explain why there would be a difference and why the genny would call for 10' more?

Thanks

Maybe they're assuming you would take the sheet through the turning block at the stern quarter and then up to the winch on the genoa but not with the jib.  Or maybe they're accounting for the thickness of the sail wrapped on the furler.   I have 55' sheets on my genoa, and  iwould not to have less than that.  I replaced my sheets 2 years ago.  I went from the 1/2" line that was on the boat when I bought it and replaced it with the recommended 7/16".  I wish i would have stuck with 1/2".  It seems like it was easier to handle and seated into the self-tailers on the winches better.

The clew on a genny is going to be significantly more aft than on a stock jib. 
Thus, the lazy sheet (i.e., the one not in use on a given tack) needs to  reach back that much further to the clew after passing around the mast.  
Ergo, longer sheets.

Because the Genoa has a longer foot than the Jib. You will need to carry the lazy sheet, further aft on the boat on the working tack side.
