I have a line that runs to a hound for a spi that I am not using what if you were to be able to connect your righting line to the spi halyard . Would'nt this pulling arc double your righting moment because your pulling so close to the top of the mast as if somone were in a boat and lifted your mast for you.
Nooooop. Re-read your Statics & Dynamics textbook. Your arrangement adds ZERO to the righting moment. Without trying to draw diagrams in ASCII chars to explain the summation of torques, suffice it to say that since the line passes over the windward (upper) hull's gunwale/gunnel, it doesn't really matter if it's tied to the mast-foot, the masthead, the shroud attach point on the leeward hull, or the shroud attach point right above your head on the windward hull--all equivalent.
Now if you had a windlass-pole, running at a 45-deg angle from the lee hull, that allowed you to hang out in mid-air, beyond the (nearly) vertical plane of the capsized hulls, THAT would increase your righting torque.
