After being married only 20 years last month I'm not going to give you marital advice like the other guys...... I haven't figured out women yet to feel qualified to give any advice.
Regarding the mainsheet system I have in the 5.5SL it goes like this. Mainsheet block is connected to the traveler car by a shackle. Other end is connected on the SL to the outhaul but I'm not sure if the uni is different. Anyway I tell my crew that they can tell if the block is right-side-up if the camlock is at the bottom (closest to the tramp). The mainsheet and the traveler line are tied together with the traveler line fed first through the camlock (attached on a swivel to the rear beam), then through the bullseye on the same swivel, then through the pulleys in the traveler car itself, then through the strap eye in the middle of the back of the rear beam. I tied a stopper "figure-eight" knot and I'm done.
Does that help?
Why do you think yours is set up wrongly?
