If you plan to be sailing in reduced light conditions make sure everyone uses the same procedure to secure a line around a cleat. If someone decides to use a fancy hitch during the day to secure a line it is easy enough to figure out how to free it up because it is right there in front of you. But when you are trying to clear an offbeat hitch in the dark, you might turn the hitch a jam because you cant see what is going on. And you might do it just when the line needs to be adjusted. For example if everyone agrees that a half hitch will be used secure a line on a cleat everyone should apply the hitch the same way every time.
