Webthe crew "by band" is very important. The NBS provides a way to calculate quite roughly what the momentum created by this crew "by band": δRM = 75*n*(3.4*B - 4.9*FS) Where n is the number of crew, B the breadth of the sailboat and FS freeboard in the vicinity of the mast. This gives us the righting moment induced by the crew. The righting WebRighting moment calculator. OK. I want to try to design a one sheeter that is likely to keep You out of water. First, I want to calculate the righting moment curves for different hull shapes, different hull proportions and different heeling angles.
