As promised here are the pics. Not saying this setup is right, wrong, or optimal. Simply what I got when I bought the boat. I assume it is representative of what AHPC was selling as an option at the time (circa 2010). I have higher resolution versions of the pics if needed.

Overview

Measurement from aft edge of front beam to center of main block eyestrap 42 ¼" = ~1.073m

Measurement from fore end of boom to turning block 40 ¼" = ~1.022m Note that the turning block straps had apparently been moved foreword approx 3 ½" from their original location. PO never mentioned why.

Tramp reinforcement (viewed from under the tramp) No idea what the second grommet is for behind the main block.
