Bruce, I did the same thing last winter with my M-17, and came up with the following setup: Johnson Marine backstay car, Mauripro Sailing part JOH38203 (I take it you already have this). Small fiddle block, Duckworks Part No. RL-378-A, shackled to an eye on the transom, Trapeze & vang cleat, Duckworks Part No. SD-002530, shackled to the backstay car. The trapeze and vang cleat has a single block and a built-in clam cleat. This was the hardest part to find, since all fiddle arrangements with attached cleat I could find were too big. Combined with the sheave on the car, this gives the effect of a fiddle block at the upper end. The control line starts at the becket on the bottom of the vang cleat, down to the lower sheave on the transom fiddle, up and around the sheave on the car, back down to the upper sheave on the transom fiddle, and back through the block in the vang cleat, where it's fastened by the clam cleat. (I think that's how it goes, but I'm not on the boat now - it's kind of obvious how to do it when you're looking at it). Very easy to get at and adjust. It turns out that the control line tension is quite modest, even when the stay is tightened down hard. I've found this arrangement works very well under tough conditions, and all the parts are small, light, and strong. Good Luck, Rick M-17 #633 Lynne L ************** One site keeps you connected to all your email: AOL Mail, Gmail, and Yahoo Mail. Try it now.
