This is why you don't cut corners on rivers. You will be left high and dry. The owners of this Sealine SC35 found this out on Saturday when they cut the corner at Dunham Dubs and landed themselves on the sand bank. There was also what we believe was a Seamaster beached at Dunham Bridge on the wrong side of the river. This is why you should have the charts to hand. They tell you where to be on the river instead of just guessing and getting it wrong!
