I have started the repair of my mast partners. I spoke to John D'Angelo quite a bit and he was kind enough to send me photos of his repair, which I scanned for him and myself.

Before cutting these up I did some exploration with a drill. I found the aluminum plate to be very solid every where I drilled. I found craking on the inside skin on the starboard aft corner of the plate.

I had to chisel through an inordinate amount of filled epoxy that was smeared over the entire area. Underneath all that epoxy I found the fiberglass had pulled away from the plate and was craked. It was very dry and surprisingly thin for an area of such high load. I think this was not built right from day one (hull #81). The plate has a crack in it emanating from the tie rod hole OR it is actually tow halve plates, I cannot really tell.

Here is what it looks like now stbd-aft corner of deck plate

Having looked at it very closesly I have drawn the following conclusions (maybe opinons would be better than conclusions).

The entire are around the partners is underengineered particularly the starboard side.

The glass work around the partner was done poorly.

A mush mast step or an over tensioned tie rod will just pull everything out of whack (I am sure this was a contributing factor on my boat) In the future I am not going to tension that rod until after the rig is tensioned to prevent the mast step loads being transmitted to the deck.

I will post more information and some photos as my project progresses.
