@fabdrol I put it there to aid in merging between boats. My thinking is that the resources are actually the same for every-one, so my chart NZ1635 == your chart NZ1635. Hence we can simply merge our resource trees and should be able to avoid dups, Or handle them with post processing. I have some ideas on this...finding resources by geo-area (notes charts etc). A right-click - look up notes for a bay?
If they are under the vessel (and maybe there are some too - vessel operation/maintenance logs?) then search across vessels is harder. 

I think we should actually make both, and wait till experience shows the way.
