The Clydagh Boat. Probably one of the most intact vessels of this age ever found anywhere (as far as I can see) A massive 37ft long, Steering oar in place, slotted duckbill bow with 2 rounded rectangular slots (for pulling ashore with oxen ?), intact fitted transom and quarter posts. Gunwhales appear full height.
These boys could build a boat. Not only that - but they could sail this monster. This doesn't appear to have been built for speed - so it was probably the bulk carrier of its day, possibly even "multi-modal", capable of being dragged when out of the water.
Probably late bronze age or early iron age (the size of the tree is a reasonably good indicator).
