Pearson 30 rig tuning
Posted 27 June 2012 - 09:31 PM
Does anyone have Spec advice for standard, single set of spreaders 1974 P30 setup would be appreciated. Have never done this before, want to learn. May "watch" someone do it first time, but I'm finding many options and different recommendations based on specific boats and racer vs. cruiser. Want performance, but won't formally race this year. Need to "learn" her first.
I've got a 100 (dacron - almost new - with racing battens), 150 (a bit long in the tooth), 160 drifter (mylar - almost new) and fully battened main (neither old or new).
Thanks for your help.
Best Regards, Rob

Let's face it. A single spreader masthead rig with a stout mast is not an arrangement that's open to a lot of subtle adjustment. Generic advice is going to get you 90% (or more) of the way. This involves making sure the mast is standing up straight and stay tensions are appropriate. Mast rake is usually set to balance the boat so you can sail upwind with a small rudder angle. You may have a backstay adjuster.
Designers specify wire for the normal working load. The book tells you how to work backward from the wire size to deduce what that is. You can get an idea of the maximum backstay tension the designer had in mind. If you follow all the recommendations, you'll have a safe boat that sails just fine.

but whatever info you can find on P30 tuning or older Catalinas, Morgans,etc should work out. Just get that telephone pole straight/plumb and snug things up and you should be fine. Let the rig stretch after first easy sail and snug her up again.
take a look at this too:
again, generic tuning for the older boat...
