I'm an excellent shot with black powder rifles. I've won awards with a musket.
I can sleep anywhere.
I've been a lifegaurd.
I can unswamp a boat.
I know most of the required knots.
I'll eat anything in a pinch.
I'm musically inclined.
I'm not afraid of heights.
I have some experience with swords.
I've lived the world over.
To name a few...ARRR!
