A well designed ship moving at 30knots can be surprisingly nimble laterally. Turn that rudder and the course will change fairly abruptly.
RN ships doing the run to Malta in WWII came under repeated dive bomber attack. They had a spotter with binoculars watching the bombs drop off the rails, and they would shout port / starboard. The ship was often able to move far enough away from the aim line in the time the bombs took to fall so that they'd miss. Of course, sheer weight of numbers would eventually count, you had to be putting up enough flak to ensure that the enemy pilots weren't keen on getting too close, and if you lost power...
San Carlos Water is a small place to manoeuvre ships. Still, the RN did a fair bit of successful bomb dodging. One of the Leander class frigates beat the Navy's speed record (they'd knocked off the engine governors on those big steam turbine plants), so I was told by one of her crew. However the Venturi effect between the ship and the shallow sea bed was strong enough to permanently bend the hull. Better bent than sunk.
