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

You sailors with your cheap extruded aluminum spars, squeezed from a cheap
aluminum extrusion die!!!

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?!?!
