a normal sized cube of 1 kg lead falls slower than a compressed smaller volume of 1 kg feathers.

Can't say I can believe this one. How can you compress feathers to be smaller than Lead?
Can't believe I might actually think Sam has a valid point here.
I'm sure you were speaking rhetorically.
However, what I want to know about is the beams. I had the old style Strap Beams, they were a pain in the butt.
A Through bolt should be better, but I would think the Flat style beams Like the Nacras use would stiffen the boat's rotation around the beam better. I know I've never had mine slip, unlike the Strap-over-Round-Tube Design.
I understand the tube is far better from a strength compression standpoint than a flat surfaced beam, but at the amount of forces we're talking about, is that really significant?
Another advantage. It is a pain in the butt to mount hardware on a round tube as opposed to the flat style beams.
