See The Macgregor yawl.

We rigged her as a double headed yawl - chopped 4ft off the mainmast and gaff rigged the mainsail as she was a bit over-canvassed for her displacement. We added wheel steering and a tab on the rudder for self steering or can run lines from the tab into the cabin. She will balance beautifully and with the many sail options makes a very weatherly rig for this stormy Lake Superior I sail single-handed. Thats our stormsail you see which is on a beartrap so we can quickly move her aside when not required.See what you can do with a Mac!!
