Just a suggestion, but couldn't you move the TI so that it is level with the front of your car so that the overhang at the rear is reduced?
Yeah, I actually want to have the main hull more forward than what is pictured, but here was my line of thinking at the time:
As loaded in the photos, the main hull's center of gravity is centered on the three supporting cross-bars. As such, there's already a lot of overhang on the hull's forward end. Being new to this sort of thing, I feared that excess overhang up front would invite the wind to catch the bow and put undue stress on the hull and/or its forward tie-downs. In short, I had visions of disaster, followed by me sitting in court answering accusations of negligence.
I had also considered getting a front hitch receiver and using a Thule Goalpost (similar to the Yakima DryDock) up front, and I still may go that route in the future. However, I would use it in combination with the Yakima DryDock on the rear, as that is what allows me to load this beast atop the vehicle.
