Abras are small Arabic fishing boats and I am informed that Dubai has a cottage industry of using these boats to transport visitors across the Dubai Creek.

Is it reasonable to expect one or more boat operators to be running after working hours? Or more succinctly, are these boats available on a 24 hour basis? Also, and critically, are there times, like Ramadan, when they do not work? Or similar occasions where taking an Abra ride might be inappropriate or disrespectful?
