Different ships, different saddles

In the good old days when gaffs lay at an angle of 45 to 50 degrees to the mast, the prime function of the gaff saddle or jaws was to accommodate the thrust of the gaff on the mast, and stop the thing falling off sideways. If you wanted to improve windward performance, you set a topsail. “Modern” gaffers tend toward the view that if you peak the gaff up higher and higher it goes better and you don’t have to muck around with topsails - the logical extension of which is Bermudan rig. It is not the place here to argue the pros and cons of high peaked gaff rig. But from the point of view of the fittings, as you peak the gaff up two things happen.
