What about the sails when Xebecs tack?

[Dobbs]

Models and paintings can't always be trusted. Artists often go more for effect than accuracy and also may not have the knowledge of the sailor.

For instance, xebecs could be rowed, but imagine the excitement if your oars were sticking out while under sail and they clipped a passing wave! It would be similar to trying to push a car with your leg while sitting in it and your friend occasionally steps in the accelerator.

There are many paintings showing sails and oars being used simultaneously.
