This sketch was buried in a bunch of S&S Dolphin drawings. We drove the pin out of Passage wih 3 guys taking turns on a 10 lb sledge and one guy holding a steel drive pin. There were no nuts. We thought it was a tapered pin with the small end on the port side so we drove it out from that side. It was not tapered.

We won't try and slam a pin out again - think about the shock on your 50 yr old keel bolts. Next time, maybe on Marionette, we will find a horizontal drill press somewhere and drill it out.

October 17, 2009. Depending on the material used to make the centerboard the pin has been made of at least 3 different materials that we know of - bronze, stainless steel and, according to John Shumaker of Yankee Yachts, a very high strength plastic material. This material had very high abrasion resistance and was just about unbreakable, and had no electrolysis issues.

We have a recently reported lost centerboard problem - Ted Prohov (Wada Boat, Yankee # 190). A pin failure is expected. We hope to learn more about this event.
