Re: standing rigging
Double (fore and aft) lowers?? maybe someone got them crossed up and you've got a fwd/aft going forward and a fwd/aft going aft.. A tape measure, a bosuns chair and some help may figure that one out...
It will also be worth your while to check that the masthead is centered on the boat. Take a halyard and stretch it to the deck, chainplate or other reference point on the deck, and see if the same point on the opposite side is the same distance. If not, the mast head is off center athwartships.. loosen your lowers and fix that by adjusting the cap (upper) shrouds.. then see how your lowers look when the mast is straight under the now-centered masthead.
