Those that can do "do" those that can't "teach"

I have issue with the way your measuring flex.

your test is measuring the flex of the beam, the beam joints and the supporting structure around the joints. but you completely failing to measure the stiffness of the hulls.

for example, when I press on the side of the capricorn it is very hard to make it flex at all but by comparison my old nacra 5.8 was very flexible in the sides.

not 100% sure on how to measure these stiffness levels but they do contribute to the overall speed of the boat!
