I have a slight vairation to this setup.
The bungee and the A section of rope is the same but my rope doesn't end at the front beam with a bead, it continues to the rear beam on both sides hugging the hull before its TIED OFF. You can then grab the line anywhere between the front and rear beam on the raised hull to manover your wieght to the best angles required and for 2 up there is room for both to grab the line.
