boats.

I think the last time I was able to do this was in the late 1950s, with
my 15' Wolverine and 25 or 33 hp Big Twin.

You need at least 5% tongue weight (boat + trailer) so for all
practical purposes you are limited to a boat/trailer combo of 3000 lbs
or so, preferably less.

Of course if you are driving at the sedate old lady speeds that you
once claimed, you could tow with 1% tongue weight. Just move your
boat aft on the trailer and drive less than 40 mph.
