Now, you make the tongue longer. That tongue has more leverage to
the piviting point (the axel). It would be easier to lift that tongue. It

the 400# you would have to move the wheels *back* more.

======================

Your analysis is correct. You could either move the axles back a
little more, or bring the boat forward. I have a similar setup to
yours: 24 ft boat, approx 5,000 lbs, tandem axle trailer about 28 ft
long. Moving the boat forward 1 foot increases tongue weight by about
300 lbs. Once you get the axles about right, it's easier to adjust
the boat position.
