Todd,
The HD eyestrap is located on the underside of the boom about 3 feet out
from the gooseneck. The boat had the boom vang when I bought it & I've
never had the HD eye strap off the boom. But, the eyestrap looks like its
attached to the boom with a pair of 10-24 UNC stainless steel machine
screws, drilled & tapped into the boom. It's been absolutely bulletproof
since 1987.
