JWMarine.co.uk - A web site all about boats and navigation. My previous book "The Bible of Boat Electrics" was published a few years ago by Adlard Coles / Bloomsbury and is still available. I am quietly proud to introduce a new one "Astro Navigation from Home" which can be bought directly from me at a cost of £10. I am in the process of setting up PayPal but for the moment please just e-mail me for more information.
I will also add a number of articles about electrics and astro navigation supporting both books over the next few months which will be free to download.
Every care has been taken as to the accuracy of the data and calculations in the worked examples. If you find a mistake, please get in contact - AJ
