Hi Jared,
Shadow,s supporting mast beams were also being depressed under the load of the main mast- the next boat will have a keel stepped mast. It wasn't till I had a professional rigger tune the rig that the forward beam cracked. I had two shipwrights take a look and both said the shrouds were tensioned too tight. Brion Toss has a DVD on tuning the rig. Anyway, Bill and I laminated a new beam out of oak and Ranndal Reeves can show you the compression post he used on Murre, which I'm putting in Shadow.
Yours truly, Kathy

Hi Jared,
Randall Reeves and I composed a "Projects" piece for installing better main mast support. I believe Randall is about to post it soon. I have installed an arched T-beam fabricated out of ss flat stock. The curved flange was 1/4" and the web was 1/2". I also added an additional section of beam below the steop so I could through bolt the bronze step and have good surface area for the fender washers below. I used 3/8" bolts with fender washers up through to the step with eye nuts on top. The eye nuts will be used for attaching blocks when I run the halyards and control lines aft. I have never had any deck deflection or compression issues with this arrangement. Cheers
