You know that the weather is bad when the Navy must seek shelter! a bad joke! In fact one of the Frigate "KNM «Roald Amundsen»" is out on the firing range and shooting (Flotex 2011), they reported that they have waves at 14 meters, while the wheelhouse is only 12 meters above the water. but they expect to get up to 30 meter waves during the night! But they have no plans to go and seek shelter.
