This is the backbone for the West Mersea One design, Dormouse. The keel is Opepe, 3 1/2 inches wide in the middle and tapered to 1 1/2 inches at the ends. The jarah apron is bronze bolted over the hog and the centreboard case installed (pictured are the through rivetted headledges). An oak sternpost is halflapped and rivetted to the keel and supports the transom.
