Now that I have important boat related info as well as additional backup Navigation aids on our iPhones and iPads I've added them to my checklist. The idea is to make sure all these info items are accessible, up-to-date and especially that the Navigational Apps are operational... as well as all being fully charged, although this can be done on the boat while underway.
I've created a folder named "Boat Info" that has all the boat related stuff in it for quick access when needed.
