There is a fish market that gets going in the pre-dawn every morning in Kê Gà village. I presume the boats in this photo are back from a night of fishing in waters near the coast. As far as I know, Vietnam does not have any of the huge factory-type fishing boats that put to sea from Japan and a number of other countries, but there are some larger Vietnamese boats that operate in deep water for days at a time. Smaller boats like these and the ones I see in Hoi An stay closer to home.
