The masts were probably made out of wood.
well, the only one Ive heard of is the longboat.
Being a Viking means going on raiding expeditions by longboat. That is considered to be terrorism or looting and murder and is no longer an acceptable thing to do.
Viking longboats were rowed with oars till they caught wind in a single large square sail.
Unlike later ships of the Age of Sail, Viking longboats had many oars, as did the earlier ships of the Roman Empire. (see the drawing in the link below)
An average Viking longboat typically had around 20 to 30 oarsmen. The exact number could vary depending on the size of the vessel, with larger longships accommodating more oarsmen. Each oar was usually handled by a single oarsman, allowing for efficient rowing and maneuverability. Additionally, the crew would include other roles such as sailors and warriors, contributing to the overall operation of the ship.
