Anchor question

  1. Boat anchor...doing the math

    Some time ago a post was made where someone explained that to help loosen a stuck anchor. Put everyone to the front of the boat, tighten the anchor rope then everyone go to the back of the boat. Excellent idea.

    So I was trying to calculate. What if: 20' long 4' wide evenly rectangular type boat that weighs 2,000# and 2 ea 200# people go to front tie off etc then go to back what is pull on anchor ? Neglecting waves, pointy front, not being able to go exactly to front, reduced pull as rope moves etc. etc.

    I come up with 400# pull up but can't prove it.
