Hi Mac,
Let me see if I understand you.
Keel weight /58---> 370/58= 6.4 cubic feet.
Designed displacement * 0.4 / 54 ---> 2000 *.4/58 = 13.8 cubic feet.
Total = 20.2 cubic feet.
I don't know what the designed displacement truly is, but I'm guestimating
that she'll be floating on her lines at 2000 pounds.
So you're saying that about 20 cubic feet of foam is all a P19 needs? I
figured it at about 30 cubic feet. Can you explain why this formula works?
If I understood the reasoning behind the formula, I could consider geting rid
of another 10 cubic feet.
Best, Judy B
