We got the bows which were apart where you could "fit the center joining one to adjust the length. I would make a mock up of the way you want it to look as mentioned here. We went with a three bow set up. The "height" of the longers bow fits about 1.5 inches under our boom.The other two bows are led off of the long bow. Web straps tightened keep the whole contraption in place solidly as well as allow for adjustment.
