[Rhodes22-list] Problem shrouds = location of answer for David

[Bill Effros]

Oh, please...

This is like a discussion of how hard to slam a car door.  You only have 
to slam it hard enough to close.  The car can take a harder slam, but 
you are not accomplishing anything good for the car by slamming the door 
harder.

We should banish Loos gauges from this list.  They are supposed to be 
calibrated for the type and size of stay they are measuring.  They don't 
measure in pounds--you interpolate index numbers.

Where the hell did 200 pounds come from, anyhow?

Is that 200 pounds when the other 8 shrouds are slack, or 200 pounds 
when the other 8 shrouds also each show 200 pounds?  Or is it 200 pounds 
total, divided by 9 shrouds?

The tension on the back stay which holds up the traveler is supposed to 
be the same as the tension on the lower side stays?

If the mast is not perpendicular to the boat, but all the stays register 
200 pounds--is the rigging ok?

A little knowledge is a dangerous thing.
