I would assume that the boat couldn't be loaded forward enough to get
the proper tongue weight without adding length to the front of the
trailer.


Hm.. I would have thought the opposite.
A longer tongue length inceases the cantalever leverage.
Therefore since the Sailboat does not have a heavy motor over the wheels,
or hanging off the back (if it was an outboard), you are now carrying more
weight in front of the axle making for a heavier tongue.
Extend the length out to increase the leverage and reduce the tongue
loading?
