The holy grail of most Cruiser /Sailors is the complete maintenance logbook, filled with details of all the systems on board, schedules for overhaul etc. etc.. I have been on very few boats who have achieved this holy grail. Most of us have a few binders containing the original manuals, a few hand written notes and the occasional half finished out of date spreadsheet. The PC should be the ideal solution, but to date I have not found any software to FORCE some sort of discipline on me. Enter "Marine Boat Solutions" . I have just bought the software so its early days yet..but it looks promising. The people at this company seem pretty responsive (I have a small delivery hiccup due to an overactive spam filter) and I look forward to future updates. You can check them out on You Tube and hopefully they will have a demo version out soon.
A Ships Logbook would be a nice addition even if it came out as a separate package.
I have no connection with this company etc.
