take it from me, 2 spin sheets a little short from cutting too much off at once. Cut no more than a foot at a time until it gets to the right length. Have the spin hoisted and try the lenght from the rear beam trapped out. Try it with the spin snuffed to make sure it will completely snuff. And if you cut it too short, you can always add a tail to the clew of the spin and tie your sheet onto that.
Your graph looks great, but I would only trust the on the boat model.
Someone on here has a sayng at the bottom of their posts that sums it all up for me.
"I cut it twice and its still too short"
The men were amazed, and said, "What kind of a man is this, that even the winds and the sea obey Him?" Matthew 8:27
