To each their own! For what it's worth, I run with my rear curtains up/off almost all the time. Even when it's REAL snotty, good amounts of water coming off the pilothouse roof, it's never wet inside the pilothouse. Only way I could think of that happening is with driving rain or a very stiff tailwind, and in that very rare case rolling the curtains down isn't a hassle. Mine have been pretty low-maintenance, it's just three rectangles of canvas/clear plastic with two straight zippers and some snaps. The boat's a '95; the canvas has been replaced once, and it's due for another. 13 years to a set of canvas, I'll take that all day long for the ability to open up the whole boat to the cockpit.
