Please check the boom angle and sail bulge of Handling sail and Weight sail in relation to wind direction. I think is "OK-ish" to one side, but disastrously wrong the other side.
Handling sail boom should always point more or less AWAY from the WIND. (Unless you press the boom by hand against the wind and you sail backwards!)
Bulge should always be AWAY from the wind like the other sails.
(You must make two alternating handling sail meshes or MIRROR sail mesh's x-axis when changing tack. you cannot just rotate all along y-axis)
On Running wind (behind) the boom can be on either side (of your choice) (90 degrees to wind) and bulge forward.
Suggesting to Google images "sail positions for points of sail"
