And I have NOT downloaded it myself.
Are we clear on that?
"a new version of the free program for designing flat bottom skiffs has
just been put in my webpage www.ncf.ca/~ag384 (http://www.ncf.ca/~ag384)
file Skiff.txt contains the instructions
file Skiff.bas contains the BASIC program
I developed new formula using 3D analytic geometry to be able to acurately
locate any point on the sheer curve. That made it possible produce a table
of offsets without and bumps in it, and add some new numbers to the
output. It also allowed me to free up the widest point from exactly midships
to anywhere in the middle third section. Which is good because boats sail
better if the widest point is aft of midships, about 55% aft of the stem.
Now that the point and distance numbers are dead accurate I want to take a
look at the area and volume calculations and see how accurate I can get
them. Its sure been taking a lot of effort to get small improvements in
the numbers. smile.gif
