Why is it nearly all CT makers have window covers on the inside? Having them like this is handy if it is cold and wet, because there is no need to go outside to do them up.
But this means that you cannot have the windows open when it's raining and it would be a pain in the hotter climates.
I had to pay extra to have storm flaps added to the windows
I had them sew them to the canvas, 200mm wider and 300mm longer than the window, they also added eyelets, guys ropes and poles.
I would have thought this would come standard, specially with the price of some of these CT's
