So there should already be a SS backing plate installed when the hull was put together?

i looked at hanz's current 5.0 and it has no real access via his 4" access ports - who knows
I actually know, but maybe not. Afterall, I just own the boat and have seen what an original one looked like when the transom ripped off in surf. Inspecting Hans' port holes seems a little invasive...maybe just ask him????

Well, after my trip to Mexico this past weekend, I feel much better about the condition of the boat. At least while it is on shore! We removed each cross beam and replaced all the hardware with spec components. Replaced all the standing rigging to include the shroud line anchor pins. And we inspected and checked the mounts for the rudders. So far, everything seems pretty solid. While inspecting the rudder (gudgeons?), I did attempt to see if the flanges fit inside the mounts..and in fact they do...like a glove. So no doubt they are currently incorrectly mounted...but seem to work. So at some point in time I will feel the need to do it right and maybe have to install an inspection port at each end of the hull to install some sort of backing plate(s).
But next step is coming up, which will be replacing all the running rigging...and then getting her back in the Sea of Cortez.
JSB4G, did you have a chance to take some pics of your barber haul this past weekend? This would be most helpful.
Heading to San Diego this weekend to take some classes....maybe fly a hull for the first time 😀

looking at the pic again, it may be as simple as the bottom gudgeons is mounted upside down -

there is an alum plate glassed in the transom (as does my cat)
you should be able to tap threads into it -
i still would simply try turning the gudgeon 180*Edited by MN3 on Sep 25, 2017 - 11:52 AM.
I applaud you for asking for advice and then passing it on instead of speculating. Did Hans put the metal plate there as a repair/upgrade? I know his rudder system is not original. Also, I have seen multiple G-Cats with the rear transom ripped off and they had to be rebuilt. I have never seen a metal plate on an original, unrebuilt Gcat. I can send you a pick of a damaged original if you'd like. what do you mean by turning the gudgeon 180 degrees?
