I’ve found a few websites that provide a few details on how to build a Viking ship. This post won’t go into much detail. Check these sites for more info that could you possibly want:

• Regia Anglopum – Making a Viking Ship – Great line-drawings of construction steps.
• Vikingskip.com – Viking ships and Norse wooden boats – How to build a Viking Ship – Principles of Norse boat building
• Viking Today Magazine – Building the Sea Stallion from Glendalough – description of building a replica of 30 metre longboat. Website doesn’t appear to have updated since around 2010.

I have a post asking How much time did it take to construct a Viking Longship?
