Stainless, Brass, or Carbon?

I’m in the process of building a new gantry out of carbon.  It looks really good (pics soon), but I’m planning on upgrading my rudder pin in the process.  Right now I’m using a ¼” stainless pin which has worked fairly well, but I’ve bent it several times so I don’t think it’s really up to the task.  For a replacement my choices are 5/16” stainless, brass, or carbon rod.  Stainless is the most obvious choice but it seems like brass may work just as well and is far easier to work with. My other choice is a solid carbon rod which would be way lighter than the metal rods but I’m not sure if it would be up to the task.  Carbon would also be able to flex without bending and could shear off without damaging the rudder.  Any advice?

Space Moth

I was looking at Google Earth yesterday and realized that the satelite photo of my area had been updated.  It was clearly a summer photo and the lake was busy so it must have been taken on a weekend.  After a bit of searching I found Mothball 1, unfortunately I wasn't sailing.  The boat was under its cover in the rigging area, so I must have been getting ready to sail.  Can you find Mothball 1?
