I would agree with "New upgrades" , but would by necessity have to make sure market recognizes they are indeed new. Having an updated (time-stamped) photos/videos showing the current status (ie great condition) with new chart plotter (or other items) would be helpful, but again this may be limited by the charter company "standardized" marketing. Unfortunately, I believe the market assumes boats beyond 5 years are 2nd tier and beyond 8 years is out of the question(Which I do not agree with, as the quality of boats really depends on ongoing maintenance).

Good luck.
