After about 6 years of use on our 2003 Marlow yacht, all of our rope lighting is due for replacement. In the photo, you can see the plastic is actually burnt and the wiring is dripping with green rust slime. Compounding the problem, the power source is 110VAC which makes it a real fire risk.
The burning color is simply due to the age of the rope light and I’m sure today’s plastic is better suited for this application; yielding a longer and safer lifespan.
Green slime? Yes! The dripping green slime is because of the high humidity in the marine environment. Many boats have problems with accelerated corrosion in the ship’s electrical system, which is mainly attributed to poor grounding.
