I've look at most of the apps mentioned above, including using a simple spreadsheet. None did everything I wanted and most were overkill for a single owner/operator.
What I want:
Systems tracking (mfg, model, year, serial number, install date, etc.) of the major systems with the ability to store multiple files such as pdf manuals of each. I want to input specific maintenance requirements (oil & filter change, fuel filter, coolant change, etc.) and have a report that gives me an upcoming/past due list of each requirement based on days and/or engine hours. And the ability to log maintenance performed, again with the ability to store invoice's, etc. for each maintenance function performed.
Inventory function.
To include mfg, part numbers, the system it's used on, and where stored onboard.
Cruise Log (Captain's Log)
To track date and place of departure, date and place of arrival, cruise leg if multiple legs on a cruise, guests onboard, notes, beginning/ending engine hours for both engines and genset, pdf/pics storage per leg or cruise, etc.
Helmsman Hours
The ability to track total hours for each person at the helm.
Fuel Expense Tracking
Miscellaneous Expense Tracking
Nothing seems to fit my needs. So, I'm building my own in Microsoft Access. I'm not a programmer or coder, just a self-taught, non-power user of Access. I'm fairly happy with what I've built so far. There are still minor bugs that need to be worked out and no doubt better and faster ways to handle some of the functions.
I'd love to port this to an app for use on my iPhone or iPad so I can ditch the Windows laptop. But hiring a tech company to do this is too expensive.
Anyway, if there is anyone out there that has more experience than me in Access and would like to collaborate or can take the Access database and port it to Apple's IOS, PM me to discuss.
Best wishes,
Bill.
