We love paperless record keeping and apps but we bet that an old-fashioned printable report (e.g. pdf) is needed from time to time. Some people/agencies still love their papers and thus you should be able to comply and get it in print for them! (e.g. this amazing mechanic of yours that thinks that mobile phones are just for making calls, some authority in need of a boat document hard-copy, etc).
Printable format (e.g. PDF) for being able to crosscheck off-screen what is needed, share with your mechanic, marina, port authorities, etc.
