In DT these last two weeks we’ve been exploring Viking longboats and looking at ways that you could hoist up the sail!
We started by putting patterns on our sails using influences from what archaeologists have learned about Viking designs and patterns.
To make life easier dealing with heavy weights, we then introduced a pulley and looked at how these can help reduce effort to maximise the load! Whilst our sails weren’t the size and weight of those on a longboat, the process of using the rope and wheels was the same. It didn’t take us long to realise you then needed a counterbalance or somewhere to fix the rope to stop it falling back down.
