You want 10% of trailer weight at the tongue. This is so that
the cg (center of gravity) of the trailer stays in front of the
trailer wheels. If it gets neutral of aft, the trailer gets
squirrely and can "ground-loop."

The all-up weight of your trailer, boat, and gear ought to be
about 1,700-1,800#. Thus, you want about 170-180# at the
tongue. Place the tongue on a bathroom scale to measure it.
