Back in the 1980s and 1990s when I was a cross-country hang glider pilot flying the competion gliders, weight was often an issue (because we had to hoof them off the mountain launch. The comp gliders were heavier because they had to be made stiffer so as not to flex too much at speed. Sure, speed, glide ratio, sink-rate, handling and landing performance were the primary considerations. But weight discussions sometimes entered the mix.
The two main manufacturers were Wills Wing in California (sort of like KTM, today), and Moyes in Australia (very Gas Gassy). The owner's son, Steve Moyes was the Nambotin of his day (and never defected , of course).
Yes, the Moyes felt a bit heavy on the ground, but in the air the Moyes GTR turned circles (quite literally) around the Wills glider and easily out-landed it.
Everyone cited the weight figures in the brochures. I had talked to the manufactures and found that Moys weightls their gliders "in the glider bag" with all the pads and bags contained inside while the other manufacturers weighed them set up with extraneous doo-dads removed.
So, one day I bought my bathroom scale to the set-up area and had people weigh them. The Moyes glider actually weighed a couple pounds less while set up than the specs stated. The other gliders all weighed the same or more, narrowing the differences to an insignificant 3 or 4 pounds.
I think I'll do the same for our next camp and ride.
