trailer carries the boat much higher to account for a weighted keel.
Doing a complete rebuild of a trailer such as converting sail/motor
you can do some tongue weight shift in the design, but a longer
tongue might be the more practical way, plus giving you the
advantage
of the longer tongue. To the guy who says his boat trailer tracks
better and is "easier to back" with the longer tongue . .
absolutely! Many yrs. as an OTR
driver teaches you that a 48' trailer backs much nicer than a 45',
and a 53' is better yet. Never tried one of those 28-30' "pups" but
know from talking to others they are a "bi*ch" to back up.

I can attest to the fact that the 28' OTR trailers are a "bi*ch" to
back, UNLESS it's with a "yard jocker".
