Mesh Statement is Vessel Definitions

[AllQuiet]

I see alot of mesh coordinate lines in all of the sub's parameter definitions and was curious how changing values resulted. For example, if a mast has a mesh coordinate of xxx, yyy.........can we change the mast position either forward or rearward by changing the values of the mesh statement. Ramius, you're probably the goto guy on this question. Please show me more precisely how I would move a mast more forward as an example. Thank you again for your dedication to the Cold Waters program.
