Dimensions of mast girder, Mark 3

[steve]

I have just had my mast girder regalvanised so I took the opportunity to measure its dimensions. I have uploaded a photo with the dimensions marked, for future reference if anyone needs them. The photo can be found in the gallery, Top Hat Mark III album, sub-album Mark III Drawings.

Excellent drawing Steve.

Now if you can add the location dimensions of the 12 fixing bolts it will be complete.

Hi Phil,
Unfortunately the girder is back on the boat and I don't think I could measure the fixing holes sufficiently accurately to be reliable. Anyone having a new girder fabricated would be better to measure the holes in their deck.

Thanks Steve.
Anybody tracking this thread will probably see your post which is all we need to do.
