Slight thread creep, but the phrase Dutch Roll is common in sailing parlance. Usually taking place on a downwind course, spinnaker set with the (strong) wind pretty much dead aft and possibly helmsman aided, a yacht can commence rolling one way, dunking the end of the boom in the water and then reverse the roll so that (sometimes) the boom can be pointing upwards 45 degrees. And if not controlled can end in a very spectacular massive gybe with the mast near horizontal. Very uncomfortable and very hairy!
I have no idea where the Dutch implication came from
