I've become interested in a high mil cover mostly for a boost in temperature. My pool is shaped rectangular 14'x39' but it is irregular, sort of a staggered width. This makes it 12' wide in a few sections. I've been thinking about buying a 12'x'20/24 cover and just covering the deep end. I figured this would actually be convenient as I could still lounge in the shallow area while it is in the pool. This would be ok right? Would it be covering enough area to raise the temperature? I get a lot of sun as it is but extending the season is enticing!
Here is a picture of my pool when it was green so you can see what I mean about the staggered width.
