Your current thinking is correct, if all things equal, AND if you
didn't consider the torsion of the spring.

What?????

The torsional forces can not have any effect on the trailer balace as long
as the wheels are round or allowed to rotate.

Bull****. Are you telling me that if you have a moment arm, and apply
a torsional spring constant to it, that it won't try to rotate about
the axis of the axle???????? If that is true, then a torsion spring,
and it's ensuing torsional constant, aren't doing any work.

Again, if you put the wheel
at the center of gravity of the boat, it will be balanced.

No, it would need to be at the center of gravity of the boat + trailer.




Trouble is,
when this is done, will the boat's C.G. be at the C.G. of the trailer?

Probably not. Which is why you would want to use the C.G. of boat + trailer
for any calculations.

Duh.....that's why I asked...geez... AND, how do you know WHERE that
center of MASS will be?


See, you could load the boat on the trailer, and the CG of the boat
could be far enough behind that the tongue has a negative load.

A universally true statement. Take any boat and trailer, load the boat far
enough back and the tongue weight will go negative.

So, now you want to talk about center of mass as opposed to center of
gravity?

What's your point?

My point is, he didn't mention the relationship between the center of
mass of the boat, and the center of mass of the trailer.
What is YOUR point? I notice you've not interjected one thing to help.
