Good answer.

The key is to get the boat floating. Back up enough to get the back end of the
boat to "bob up". Note the depth of the trailer at that point. When
I retrieve my boats, I usually have the trailer a little more shallow than
the "float point" so it'll self center on the trailer. For my small I/O,
that's usually when the fender of the trailer is about 2 inches out
of the water.

However, every boat, trailer and ramp behaves differently so you'll have
to get to know your setup.
