Not sure what exactly you are asking about, but I added some pics of mine in a new gallery called, cleverly, Mast Base. I think this is the original set up. There is a tombstone shaped shoe that fits into the mast and is secured by 4 screws through the mast wall into the shoe. The tilting mast base unit then bolts to the shoe with 4 screws.

I try to remove the base every year and clean it up because the base of the mast seems like it would be a very harsh environment. It was a bear to disassemble the first time but is pretty smooth now. The shoe had some stripped holes, so I have re-drilled a couple to the next size up and re-tapped. I use LanoCote as an anti-seize when reassembling but I know others swear by other products.

:: Hello,

:: Does anyone has photos of their mast base, on deck and
:: inside the base of the mast section?

:: Ballenger explains some sort of tubing (square tubing

:: screwed onto the stainless plate and into which is the
:: section is simply in place with a bolt going through the

:: I need photos to better understand the mod.
