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.
