Multi Point Lifting Sling Vectors

My neighbor has a fishing boat and wants to add four lifting points so he can launch at a rather extreme harbor on the Oregon coast. Appropriate length slings are required to keep the boat level, considering that the center of gravity (CG) is aft of the boat’s mid point. I got a solution for two lifting points first, then struggled to solve for three and four lifting points, all the while hoping for a generalized solution that eluded me. My four point solution works and the distance between e…

But I don’t have Karamba3D? Was surprised that calculations for a 3-point lift are so complicated.
