Interpretations
Near Stern Structure/shape Inside of the the hole, curvatures of wooden structure suggest that shape of this area is very similar to water-run/deadwood area of wooden sailing vessels.
Interpretations
Keel And close to the end of field season of 2014, the team find keel timber beneath the heavily framed area. This timber shows uniquely shaped grooves called rabbets where receive garboard strakes of hull planking.
