While in the U.S. Navy, the ship I was on, U.S.S. Goldsborough DDG 20, was in the same typhoon (name for Pacific hurricane) for ten days straight. It was traveling the same direction we were, westerly. We were in and out of the eye several times and it is indeed calm weather wise but the seas are still very disturbed. The signal bridge was 120 feet above the waterline on the guided missile destroyer and we took green water over the top of it. The ride was so rough that virtually everyone on board was seasick at one time or another, even "old salts" with thirty years in service. We took rolls of at least 55 degrees and sustained a lot of topside damage from the force of the water.
