Hi, we have a Ted Brewer corten 42 Gaff Schooner "Southpaw", purchased July 2014 in New Zealand. She was built by Jeffersen Marine Oregon.
When purchased she was on the hard undergoing a rebuild. I have a box full of running rigging bits and pieces and would love some layout photos of where the block anchor points are and where sheets are run from the jibs and mizzen back to the cockpit. She's a lovely craft. Jim and Chris.
I suspect that we're talking about two very different Brewer boats. The Brewer 42 in the original post is most likely to be a variation of the Whitby 42, a fiberglass build quite different from your boat.
Anyway, welcome to SN and best of luck finding other owners of any existing sister ships!
