The vikings were exerting themselves to build boats and I think they designed the boats cool.And they made boats long, like 16 to 37m that is all I know about sailing but I think that sailing is cool but I wouldn't want to do that in real life.
Viking is hard working because like they make house and if they don't make home thin they will not sleep on and will get cold they are going to be cold if they don't work some time they dont want to do it stuff
