Is it really all that hard to figure that not all swim platforms are created equal? ( size, shape, strength, repair.....)
Or variables about the docks you need to pivot away from can complicate things?
Or that different amounts of everage and therefore force may be required to accomplish what you need to overcome the wind or current?
So many ifs on a forward after spring. I think usually less so on an after bow spring...but still quite a few ifs.
Lastly is some boats and crews are difficult to spring because of layouts, shapes, number of crew, dock hands available or not, location of places to run the spring to....
Actually most boats have so much flare to the bow it makes springing on the bow difficult. You are correct however that each situation is unique so unless you only tie up in the same place in the same wind, same crew, current and tide level it appears some flexibility may be useful, that's why I have more than just a screwdriver in my toolbox and why I referenced seamanship.
