Am I the only one that has no curtains? Why do you need curtains?
I find them advantageous to reduce light levels aboard for daytime sleeping: either an afternoon snooze, or a serious catching up of sleep if I've been awake most or all night (for good reasons or bad!).
At night they reduce the loss of heat from the boat, in dark anchorages and moorings reduce general light pollution and improve the view from my own cockpit and from others' boats, and underway stop light from the interior spoiling my night vision.
Keeping them closed when the boat is not in use also reduces the UV damage to the interior (possibly of less concern to those whose boats are younger than mine).
