Traditional Gaff Rigging "Rules of Thumb"

[benz]

I'm not sure there is any standard work specific to small schooners--you seem to have the standard resources already. There are schooners of every size and description where I live, and all of them are rigged differently. I think you'll have to figure out the loads and use engineering principles to see what blocks and line to use. You may have to consult with a naval architect to calculate any loads you can't sort out from Skene's or the Apprentice. But don't be afraid to make your rig unique--do your best with the information you have available, and be willing to tweak things as you sail. After thousands of miles with my homemade gaff rig, I'm still tweaking things here and there.
