We all know they both have two masts, the mainmast being ahead of the mizzen and considerably larger, but which boat is which, and how to remember it? The answer is that, in a yacht, the ketch steps her mizzen forward of the rudder post, while the yawl’s is abaft it. ‘Yawl’ rhymes with ‘’haul’, so if you remember that she’s hauling her mizzen along behind her, as it were, you’ll never be in doubt again.
