Hi Vince and Sharon,

 

 In regards to your pivot pin,  I did exactly what you were suggesting with a stainless steel bolt.  I suppose it might be a slight drag, but from what I've seen sailing with other boats, Tullamore has no problems with speed.  It also makes the job much easier when it comes time to replace the line that raises and lowers the board.  My original pin actually was a flush mount bolt (like a screw) that bedded in flush in an indent in the keel, but didn't go clear through. It just threaded into the keel itself. Over time those threads stripped out, so I drilled it all the way through, sealed it from leaks, and put in the bolt. Be sure the non-threaded part of the bolt is long enough to reach past the centerboard so the threads don't chew on it.
