Bill is skippering his pride and joy, a lovely 50 foot long working trawler, fully and lovingly restored to her former glory. A trip is organised and Bill finds himself assisted by assorted weekend sailors, some of whom are useful, others decorative. Lucinda, a rather snobbish solicitor, irritates him by being rude and unhelpful, and laughs at him when he becomes angry. Finally he can contain himself no longer, and gives her exactly what she needs - a spanking. It does the trick and romance soon blossoms on board, but Bill is left bereft when he fails to hear from Lucinda for several weeks after the holiday ends. However, the relationship picks up again, passions ignite, and there are more spankings - and before long Bill gets to meet Lucinda's parents and a whole new future.
