[Corsair]

Well, the "Corsair" nickname comes from :
1. My 20 past years devoted to flight sims, and today mostly props in IL2/PF where the F4U is one of the planes I like flying most when I fly US Marines- with the P38 on the USAAF side and the F6F5 for the Navy...
2. My hometown St Malo in France, besides being home of Jacques Cartier who discovered Canada has also a long tradition of pirates and privateers sailing on all the seas around the globe (which explains also the skull and bones flag on my subs)

SH3 Gen only affects your first save of a patrol and makes a backup anyway, it is not touching anything in the game code. You run it only once / patrol.
SH3 Weather does, but you can save a copy of your original Campaign files -see the readme- so you can just reinstall them if you're not happy. You get weather changes more often, corresponding to the month you're in - which you enter when leaving for patrol -and avoid crazy things like Heavy Fog with 15 m/ winds... You also only run it once per patrol.

PS : the SH3 weather driving me mad refers to my last mission - see AAR under post "Visit Bristol" from a couple days ago where the fog coming in and out and in again nearly drove me to abuse of the schnaps bottle in the Kapt'ns locker...
