The 12’6″ version of the Northumbrian Coble uses a gunter rig and has a beam of 4’11”. She uses 6mm (1/4″) ply – around 5 sheets and has an approx. weight of 120 lbs. Her high forward freeboard and veed forward sections means that she will throw off water in rough seas. Like her smaller sister, she has tumblehome in her topsides from amidships aft making her easy to row whilst giving a generous waterline beam and stable sections.
