Tony,
Trouble !! <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> I don't see how the system worked when the diamonds were mounted above the hounds. As Jalani says the trapeze wires will be working against the natural mast rotation axis and inducing more stress. This is definitely not good. <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" /> <img src="http://www.catsailor.com/forums/images/graemlins/crazy.gif" alt="" />
The diamond wire mountings also look very bulky and appears to stick out too far from the mast. My existing mast has the swaging built into a Ronstan flat bar fitting that was then bent to allow just sufficient space for the swaging to contact the mast. The trouble with that is that you can't see the mast or clean it or see what corrosion has been progressing. I'll definitely be going for the T Ball fittings with my new mast.
Regards,
Peter
