The Sail That Was as Big as a House
A Viking longship's main sail could be over 100 square meters!
Forget tiny triangles- a big Viking longship could sport a massive square sail, sometimes covering over 100 square meters! That's huge for a ship meant to be fast.
These sails were often made from rough, densely woven wool cloth (called vaðmál) or sometimes flax. Imagine weaving that much fabric just for one sail!
The mast holding this giant sail could be up to 13 meters (about 43 feet) tall! It had to be strong but removable, sitting right on the keel.
Because the sail was so big, it took many hands to raise and lower it safely when they needed to switch to rowing.
