No John.. I believe Doug's premise is that a properly engineered vang can
equal the capacity of a topping lift... that I dispute.

Excellent ... then we are in agreement

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.... but not
the topping lift. The weight of a man on the end of a boom on the 50 foot
boat would not tax the vang.... nuff said.
Not that I never

Not unless you decide to compare mechanical capacities between the vang and
the topping lift
One last point, if you retrofit a rigid vang to you boat
| you still have a topping lift to use for things like hoisting someone to
the
| masthead, or hoisting an auxiliary out of your engine compartment, etc.
BTW,

Yes.... I concur ... but the discussion was regarding the capacity of the
vang compared to the topping lift. Both have their functions... and for
hoisting the topping lift has the advantage by a large margin.
