J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Rig Tune

Rob - the conversion chart is direct from the Loos web site. I just deleted the other models so there is less confusion. The PT-2 scale only goes to 40. The Model B (which is the Model 90) goes higher than the PT-2. You'll find the tuning you have is very tight and I think most don't tune the rig that tightly.
