“In each section of hull, there will be no point of underwater body below 0.3 cm another point of the same section located closer to the centreline axis of the hull”
But the diagram in appendix 1 has got me confused. There are 2 places where it measures 0.3cm… the first is for the hollow underside… that one I understand. The other appears to be from the waterline to a flat-spot on the bottom of the hull. That one I do not understand. What is that one about? (It’s on the left side of the picture, FWIW, and here’s a link to the appendix : http://rg65.rcsailing.net/wp-content/uploads/2009/06/appendix1.gif )
Thanks, Earl. The picture at your link makes way more sense. I suspect that the picture in the appendix isn’t drawn quite correctly, since the “0.3cm” marking on the left does not appear to be a hollow, but rather a flat spot, and the rule doesn’t seem to outlaw flat spots, just hollows?
