I deleted the other thread for you....
Whether or not a triple spreader rig offers you an advantage or not depends on what you're after.... and on the boat in question.
Generally triple spreader rigs are a smaller mast section for less windage, less weight aloft and less heeling moment. They also allow a narrower spreader width and therefore tighter sheeting angles and theoretically improved pointing. But the rest of the boat and rig have to be designed with all that in mind.
Certainly a double spreader or even single spreader rig (up to a point) can be made as strong, but at a possibly considerable weight penalty. On certain boats it would not be an issue.. on others it might change it's performance and behaviour quite a bit.
Putting a triple spreader rig on a Westsail 32 or even a Catalina 36 might not prove worthwhile... it's actually quite rare to see a triple spreader rig on a boat that wasn't performance-oriented (read at least racer/cruiser if not outright racer) in the first place.
So - any advantage for your typical 36 ft coastal cruiser? Likely not.... have you seen one so equipped?
