nav lights
The international standards are laid down in what are known as "colregs" (International rules for prevention of collision at sea). Unlike cars they do not seem to give dimensions as such but quote visibility distances so achieving that may demand a certain height. It seems there may be a minimum height associated with any lights that are required to be fitted on a mast. The rules alter slightly according to length. My interpretation is that you need port & starboard side lights, a masthead light, a stern light and an anchor light, all at the required power and visibility. I strongly suspect the RYA will sell you a guide. There is a fair bit on the internet but have a look at these two links. Remember to put them on one line. http://www.solentmarine.co.uk/acatalog/AS-S40-41 -42-50-Mounting.pdf and another: http://www.boatsafe.com/nauticalknowhow/boating/ colregs.html. I can not be sure about any internal rules for European Countries so it would be a good idea to ensure you know the individual requirements. However I suspect any differences would be less than Colreg requirements for a single vessel but may have additional requirements for things like barge trains. Tony Brooks
