Hi,

Your picture shows a replica of a Viking boat built by some enthusiasts here in Sweden.
Unlike the original, this one is motor powered and is often used to transport tourists around the Stockholm's archipelago.
I'm not sure whether it 's exactly like the vessels used by Leif Ericson though…
A Viking boat replica was built and sailed down to Seville (Spain) where she sunk during Mediterranean's hard weather, just before she reached the Spanish arbour (all onboard were rescued).
That caused some people to wonder whether the Viking sailboats were seaworthy enough to cross the rough waters of the North Atlantic…

Cheers,
