Subject: loads on masts


Hello,
need to get some data on load figures on masts for sail boats.
Various pulling forces from forestay, halyards,shrouds , backstays etc
plus
pushing forces from spreaders
act on the mast.
Need some real numbers in lbs for standing rigging as well as under sail
for
variable conditions.

Of course each boat and size have different value ranges.
Have looked into various books but real data are scant.
Can somebody help with links or bits of wisdom? Just assume and make
references to boat length , mast heights etc.
help is much appreciated
thanks mik

Well, one way to look at it is that the torque cannot exceed the righting
moment of the boat. It may be easier to guesstimate the righting moment of
a boat than aerodynamic forces.

I am not a naval architect (or marine engineer).
