How do you tension D2, I have a stemball on one end and a marine eye on the other. The only way I can figure is when you put tension on V1 and RD1 thru use of there turnbuckles the resulent vector is applied to D2. I use as a reference Http://kobernus.com/H260_/checklists.htm and Http://ayesail.net/sailing/MAST_TENSIONING_PROCEDURE.htm Thanks John
