We all know standing rigging is tarred (black) for protection and running rigging is left natural because it is handled. However, every model ship I see had both the shrouds and ratlines tarred (black). I can see the shrouds tarred as standing rigging but why the ratlines? The ratlines are constantly handled by the crew and I don’t think they want tar on their hands and feet. In fact, the ship would be a mess in short order with tar transferred to all the running rigging and the ship’s deck. I have been known to miss the point from time to time (just ask my wife) so if someone could set me straight I would appreciate it. Should ratlines be left natural?
