The new dual axle trailer is coming along. IR now a welder. I could
use some basic math help around figuring out where to place the boat's
center of balance on the trailer. (so I can put the bunks in place) If
it were exactly between the two axles then it would have zero % tongue
weight. Is this correct?
There seem to be several schools of thought around what percentage of
tongue weight is ideal, proper or even workable. Let's say you picked
10% as your goal,..
My question then is how far would you move the boat's center of
balance forward to obtain this?
Also, does going up or down hill change this? If so how do you allow
for that?
The boat is 23' on deck and approx 4300lbs if that makes a difference.
The tow vehicle is a 3/4 ton chevy with a tow package.
Thanks for your time as always.

Rule of thumb is 2/3 of the weight in front of the trailer axle, the
other half behind it.

Good luck figuring out how to do that!

If the boat and trailer are properly matched, it pretty much happens
automatically. But with dual axles, it's less important. Still, the 2/3 1/3
rule should fall between the two axles.
