Huh ??? Why so difficult with 2 or 4 scales?
Just place the cat on the trailer and lift one hull up somewhere in the middle. then you shift a box or something else with the weighting scale on it under the hull.
Do the same on the other side (on the same place of the other hull!
Add and done!
accuracy = 2 x scale accuracy + 2 x reading accuracy (only with analog scale)
