Mike, I'm not sure that halfway between the lifting point equals the center of gravity. The lifting points are placed over interior bulkheads, and that's probably more for support reasons than for balance.
The Travel-lift that the marina used to load my boat had scales built into the straps, and the weight on the two straps was not the same, and the straps were pretty much on the lifting points. When they loaded the boat on the trailer, they just watched the rear of the truck to estimate how much tongue weight they had, and adjusted fore and aft from there. I think the rule of thumb is the tongue weight needs to be about 10% of the gross weight. Without a scale though, it's just a guess. I suppose you could load the tailgate with 700 lbs (4 large friends ought to do it) and measure how much the springs compress, then adjust the boat/trailer to match that.
