If you go to jeanneau owners network - Home
there are over a dozen folks that regularly post about sailing there 36i's, both P and non P models. Overall, folks are not liking the shoal draft, prefering the std at a minimum, or the deeper version overall. For me, it would be a P deep draft keel model. There are a couple that are racing there rigs, along with a number that have done some pretty nifty mods to them too. Right now that sight has more 36i folks posting, with 39i behind, then different versions of the DS models.
and if you go to http://jeanneau.tripod.com/
you can find polars for the 36i vs 36iP in the specs area. If you can not find them, email or pm me and I can send you the pdf files that are on that site.
