Some years ago I volunteered sailing the biggest Viking ship built in modern times. It was a funny experience, but very very hard taking into account that everything was done by hand.
The ship is now in America, and anyone who feels for it can apply as crew. Visit the homesite and sign up, maybe you are among the lucky ones who will be chosen: https://www.drakenhh.com
You can see me in this video at 1.49 with my baird and shirt with white arms - in less than a second.
