Cor 360lbs plus, you are going to be well down on the waterline marks.
JP advises to set the diamond wire more on the water than by loos guage, just set the windward wire to be just going loose when out trapezeing, the carbon mast is pretty forgiving but you may be pretty over ballasted at 180 for a crew.
A good starting point, maybe just tension it up a tad plus a couple of turns on the nut and then test drive.
