Did you use the CG formulas on this site or are they more or less occupying factory location of a single tank along the keel?

I did do a bunch of math and used the CG table on the site - but it's tough because I really didn't have all the given data from the original rig and never rode in the boat before taking it apart, so have no idea how it rode before.

Most say that, if you're adding a bracket, try pushing the tank as far forward as possible? I went from a single 100 gallon tank to twin 62 gallons, and the CG of the "tank assembly" is moved up around 18 inches - the front of the forward tank is about 24-25 inches up from the original tank.
