Other crew members included a helmsmen, who steered the ship; a lookout who watched for rocks in shallow waters and a few spare men who took the place a tired oarsmen or replaced one lost overboard during a storm.

The Berserker One Viking word that entered our language was berserk. It was used to name a type of Vikings fighter.

Sometimes this was done by shouting battle whoops,

As the longship neared a beach,

warriors, called "berserkers" would go over the side,

shouting and waving their swords in anticipation of a battle.

This too created fear in their enemies. Some berserkers were so worked up, they jumped too soon and downed in water over their heads.

This fury, which was called berserkergang, occurred not only in the heat of battle, but also during laborious work. Men who were thus seized performed things which otherwise seemed impossible for human power.

They used the sun's location above the horizon at sunrise to determine east, its position at noon to determine north and south and its location at sunset to determine west sailing directions. During foggy and cloudy days, they used a special stone called a "sun stone" to help them locate the sun's position. This stone, really a calcite mineral called Icelandic spar, would change color slightly as it was turned in the light. A certain color marked the position of the sun even through fog and cloud cover.
