Well finally finished the Boat Logger electronic log book web site and have managed to work out how it all fits together. Quite happy with my results and think the pages are informative and pleasing to view.
The Ownership page has some useful records of work on the boat and also (viewable to me only) the total running cost of boating these days!
All we have to do now is get Kevayling underway and see if the wireless tablet on-board which holds the logging software actually works and sends the data to the web site. I'm hopeful that it will.
