And you're wrong.

Allow me to put to you 2 separate scenarios... a rigid vang on a 20
footer
and a rigid vang on a 50 footer. Now... on the 20 footer it's obvious the
weight of a man on the end of the boom would tax the rigid vang....


Not necessarily. It depends entirely on how the rig is built.

Ever seen a man standing at the end of a _real_ 20' boat boom supported
by just a rigid vang? Can you imagine it's bend? Try it on you dinghy
-that's about 20' -and you can block up the boom at the vang position.
Then send us the picture -since you are so sure it'll work OK!
