nope, it means you don't need an inflatable saucer no matter what type of boat
you sail or drive.

read it again.

ganz, read it again, this time slowly and out loud.

you don't need training wheels not to need an inflatable rubber saucer,
aka
liferaft.


Let's try to translate this......

Inflatable rubber saucer = liferaft

The two negatives ("don't" and "not to") cancel each other out, so it's
quite easy, really.

"You need training wheels to need a liferaft."

Did I get it right, Jax?
