Longships.
The viking boats were called tall ships
The Vikings used longboats to cross the seas.
Viking boats i believe were called longboats, with a sort of weird swan shaped front and back. The vikings would sit and row in synchronisation at a fast pace, which is why they were superb invaders!
War boats were called triremes.
The Vikings' boats had one sail because they also had oars with which to row.
If you're talking about the Viking "long boats", the Vikings used them for raiding foreign lands. Raiding is a form of warfare.
