I'm worried that if the CG isn't somewhere relatively near the center of the lift, it's going to strain the lift and the boat, and could be ugly if a hurricane comes through.

You want the lift bunks to extend aft to the transom. On my full cabin 40' Formula I'd guess the cg is about 15' from the transom (pretty much under the driver seat) based on my crude estimation of where to put it on the lift so the tension in the fore/aft cables is the same.
By the way, you can make the lift bunks extend behind the lift cross beams as needed to get the bunks to run to the transom and keep the cg between the two cross beams.

Wicked Won,
How did you measure your CG? Do you have to use a sling at a boatyard or is there some "backyard" way of doing it that the average person can do in their driveway? I have a 38 that I want to measure.
Thx

Thanks for all your help guys.

Backing it in is an interesting idea, but I don't think I could get the cradle down enough in low tide to clear the drives.
