I recently replaced the steering cable between the flybridge and the lower helm on Archimedes, our Grand Banks 42. The project was surprisingly easy and inexpensive. Since many of our Grand Banks are getting on in years, I though the process might be of interest. It’s a fairly long post. Rather than post it all here, I’ll just point you to my blog for all the details.
