'桅' is short for '桅杆', which is mast. So '双桅' means two-masted. '呶呶嘴' literaly means 'Pout lips'(no sexual meaning here). It means instead of pointing that sailboat by hand, some one point the lips to the sailboat instead. Some time I do this kind of things when I'm being lazy or my hands are occupied.
