I'm going to buy (or factory order) a new trailer for my old 20' o/b

What is the boat? Is if fiberglass?

First, they don't build anything but "float on" trailers anymore...

I assume "float-on" means the boat floats on to (above) the trailer and
the trailer comes up under it when the tow vehicle pulls it out of the
water? What would non-float on be, powering it on??

Second, nobody worries about supporting transoms with the frame of the
trailer anymore. They see no problem with hanging a transom and its
400 lb o/b way back past the rear trailer cross brace

This is one of the reasons we looked for custom welders and then finally
built our own trailer. The "off-the-shelf" trailers would likely have had
our
transom hanging out past the end. We have a 50 galon gas tank right there.
I didn't want all that weight leveraging on my wooden stringers constantly.


If you do have to get a trailer where the transom hangs off the end,
consider
blocking up your transom when the boat is not in use for extended periods
of time.
