I'm looking at Iain's John Dory construction plan trying to figure out his kick up rudder. My scanner won't scan the drawing, so I hope those with the plans or who can picture then can help me understand how he works the downhaul.
It is clear to me that it comes 'round a cheek block at the top of the rudder head but then I am not sure what it does. At the bottom of the rudder box close to the waterline he shows it go around another block and then tie to a pin in the centerboard inside the box. But as drawn that part of the box looks solid, not hollow. So is the lower bock inside the box or outside or what?? I'll try to get this thing to scan.
