THE TECHNICAL BOAT FORUM FOR ALL YOUR ANSWERS

Are you looking for good advice about sailboats and yacht equipment and systems? Why not invest in one of my sailing yacht books? It will save you money and valuable time. All you need to know about your sailing yacht or trawler yacht and motor yacht systems. From marine electrical and electronics systems to plumbing and sail handling, this is the place to find it. If you are purchasing a used-boat, or have boat-for-sale, or plan to take a yacht-charter, all the information you will need is here at the boat forum

So where do you start? There is a lot to know. I get asked regularly about what is the problem, and more importantly and how to fix a problem. I am a yacht owner and that’s why I have published a dozen books to tell you all that you need to know about how to take care of your sailboats and yacht systems.

My name is JOHN C PAYNE, and many of you may already have one of my books on marine electrical and electronics systems (The recently published Marine Electrical and Electronics Bible now in it’s 3rd Edition) or perhaps one of the many other books on sailboats and yacht systems. I am not an armchair expert, but a qualified and practicing marine electrician and engineer, and a marine surveyor. I do this for a living, and also I sail and cruise my own yacht for fun! I have built, lived aboard and cruised several yachts and the chances are that your problems have been my own. Let me help you with the boat forum!

What is your yacht problem? If you know what the problem is then we are halfway towards finding you the right solution. Why not choose from one of my many books to help you fix your problems. Here are some hot topics for the boat forum:

Battery Charging How to keep the power on and solve battery charging problems

Lightning Protection How to keep you and your boat safe

Lighting Systems How to keep things well illuminated even on the darkest night

Boat Wiring How to keep all your electrical powered systems operational and how to locate faults when it does not

Inverters How to get AC power on your yacht

GPS How to get the best from you GPS

Engines How to make sure your engine starts every time and how to fix it when it doesn’t

Interference How to locate and eliminate that annoying radio noise
