Craig,
FWIW, I'm #210 and I've also snapped two carbon booms right at the harness
line connection, although one was during a grande slam (in which I also
broke a rib - not carbon, but a calcium alloy). These were older FS, not
chinook. When you look at the tube wall thickness and consider the point
loading by the straps, I think they should add some wall thickness in
that
area (also where the bending moment is greater). However, I'd never use
an
aluminum boom on a larger sail - they're simply way to soft in gusty
conditions and will break too (I've broken several Al rental booms),
albeit
with a little warning sometimes.
Good luck with the replacement. If you can afford it, stay with the
carbon.
