This was an article done some time ago now, that I indicated that I would post a link to on the A30 List.
Here it is. Included in the article are rigging tensions that were done from a survey and are included in the A30 Maintenance Manual, and on the web site.

Thanks for the details on the rigging. I’ve stuffed that into my Alberg folder for that time ahead. I’m new to the Alberg and am gathering info on the masthead’s rigging periphanalia, sheave, blocks, and a couple of guys on the board have been very helpful so far. Trying to figure if it is protocol to not run any lines up through the mast. Also trying to figure out the sheave’s popularity as it apparently permits a line to jump or seize? Any additional insights from you on these would be very helpful. Most of my renovation of hull #614 is posted on my blog baggywrinkles etc…
