If you need J/30 rigging in the Annapolis area, I would suggest talking to Gordon Latrobe. He used to own and race "Shaken Not Stirred" and is a great guy to work with. He owns Northern Bay Rigging and is, of course, very familiar with the J/30 rig. He should be able to set you up with whatever you need. His number is 410-626-8855..and here's the web URL:
