The submerged boat at Epagnette, in the river Somme (Picardy, France), has been the subject of a scheduled subaquatic excavation since 2011. The present paper gives the first interim report (2011-2016) on this excavation of a river boat. The hull, constructed “sur sole”, i.e. above a flat bottom, displays certain original types of joints between the lower planks (“mi-bois”, i.e. half timber joining). The sides are clinker built. In the wreck, dated from the mid-18th century, a large part of the cargo of tiles was preserved still in place, a particularity which helps to determine how the freight had been stowed.
