"Two. We sail north, try to go around the British Isles and find a port in north Germany. We could fight our way south from there. But I advise against it. That's what the British want. They have to be low on jet fuel, maybe close to out. But their subs and half their destroyers are nuclear; assuming they have enough survivors to operate even some of them, they can field a small fleet. Off the coast of Britain, between their sea and air power, they could take us easily."
