Duet - A Yawl

Isn't this an elegant yacht? Spotted on the River Orwell today. I will have to update when I have got the names of the sails all sorted, but I know that there is the flying jib, mainsail and missen. Not quite sure what the jib behind the flying jib is called though. Wikipedia says: "A yawl is a two-masted sailing craft whose mizzen, or aft-most mast, is shorter than the mainmast. The word yawl was first recorded in the 1600s and derives from the Dutch jol. Historically the term was also used for a ship's boat with oars".[1]
