You're talking about the 531 double butted tubing. Double butted tubing can
be thicker in the ends or the middle.
Bobsprit is double butted and his tubing hangs in the middle!

BWAAAAHAAAA!!!!!!

Good Lord. Last double butted tube I saw was thicker at the ends. Guess
Reynolds got it all wrong...

Cheap, cheap, cheap! And not efficient at all!

The finest spars, aside from composites, is Simple Simon's double butted
pre
stressed boom! Yes, that's right! The finest steel bike frames are
made
from double or even triple butted tubing. The knowing Captain has
himself,
with his very own hands, constructed a double butted boom. It's tubing
wall
is thicker in the middle rather than on the ends! It's pre stressed to
overcome tensile loading! Only a genius could design such technology.

It's a shame that the good Captain is too modest to tell you these
things
himself. It's a worse shame that you all are too ignorant to know it in
the
first place. But the worse shame is the lack of respect you all have for
the
good, noble Captain! Can't you all appreciate the great things in
life?!?!
