River sailing boat

These boats are typical of the Loire and were used for ferrying goods up and down the river.
They're clinker-built and flat-bottomed and are known as "gabares". All sorts of additions have been done to the topsides as originally they were open boats. They carry one big square sail normally in a "square" rig rather than fore and aft.

Tourists use them now for river trips - worth doing if you're ever in the area!
