Re: Windows in a jib....
Well I opted to NOT get one. Talked to the manufacturer and he basically said it's a personal preference thing.. This is on my 155 load path sail. I have to admit, I have to sit low side to see around the beast. Since I usually am only racing with it, there are several of us "watching" around it. NO doubt a window would help. But for the reasons stated here, the windows can easily create problems something I wasn't real keen on for a new sail. You can kind of see why it's a problem here:
