even though the hangar bay is about 15 feet above the water , the seas are rising and coming up to the deck level , and you all ooh and aah as they rise and fall , with the ship leaping through some of them and diving through others , and coming over hard and the helos straining against their tie-down chains , and someone says the skipper is making sure we hit rota tomorrow and someone says for what , more beer on the pier and then you look out over the waves and see one build on another and rise up above the deck level and you back off .
