Wet Raincoats On Shabbos
Drying a wet garment is an issur of Sechita, cleaning the garment.  However if you are not makpid on the garment getting wet, then drying it lightly is permitted.  Therefore says the Shmiras Shabbos K'Hilchoso (15:34), when you come inside from the rain with a wet raincoat you may lightly brush off the water since you are not makpid because it is made for the rain.  If it is made of plastic or nylon then you may dry it however you want.  Since the water does not seep into the material it is not sechita.

Regarding the issur of hanging it on the line since people may think you did the laundry on Shabbos, the Shmiras Shabbos K'Hilchoso says that even a plastic raincoat cannot be hung in a special place to dry.  However it may be hung in its regular place such as a closet.  In footnote 119 he brings that Rav Shlomo Zalman permitted hanging it to dry because whoever sees it knows that it is a raincoat that got wet from the rain and was not washed on Shabbos.
