I think BN means "Boat nerd", or something like that! I used to run a canoe/kayak race and we had two special trophies; Ugliest dog and the DFL trophy. It was huge race and there were always several dogs with the spectators. One year a sweet old lady in her 80's finished last and received the trophy- she looked puzzled and asked what DFL meant. Her husband quickly stepped in and said 'did finish last", and saved the day. I thought it pretty clever. jerry ----- Original Message ----- From: "Tom Jenkins" <tjenk@gte.net> To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Sent: Saturday, May 05, 2012 12:46 PM Subject: Re: M_Boats: centerboard pin Thanks, Jerry. It is probably a good idea to watch everything at all times, if you can figure out the meaning of what you see. I know it is not industry practice, but it would really be sweet if manufacturers supplied first buyers with diagrams/drawings and specs for everything on the boat, with suggestions as to what might deteriorate or fail from wear. BTW, I don't know what a BN is, but my Google search suggests "Brief Nudity" or "Bangledesh Navy", both of which would make one an expert on austinetic processes :-) TJ On May 5, 2012, at 12:21 PM, jerry montgomery wrote:
Probably nothing to worry about, but it be smart to watch it. The pin was probably not passivated and it's just some interior iron bleeding out- something to do with an austinetic process, blah blah. If Sal is listening he knows all this stuff about stainless. The last time I saw Sal he was headed to MIT to give a lecture on stainless to the engineering dept! I did read a book on metals about 45 years ago when I decided I was going to be a BN, but all I remember are a few of the really short words.

Greetings, I have a 2004 M17, and following a week in San Diego Bay I noticed what appears to new rust stain around the centerboard pin on one side. Is there something in the hidden apparatus to be concerned about? I know the pin is stainless, and stainless can rust a bit, but it has never happened on longer immersions in salt water.
