War of 1812 Navigation
Master Chief Jeff Ryan of the US Coast Guard demonstrated
some of the navigational gear used during the War of 1812 including an Octant
and Traverse Board. You needed to know trigonometry to sail these ships.
He also explained the roots of the expressions Deep Six and Mark Twain. From Navy Week 2012 in Cleveland.
