years of additions, removals, abuse, and misguided McGyverisms, no
system on board harbors greater potential for starting a fire than your
vessel's electrical system. Here's a good example of what we're
talking about - a splice in the main AC power feed (between deck
receptacle and main panel) made by simply twisting the wires together
and covering it with electrical tape (more is better, right?).
Splices are not recommended here and if they were, you'd at least want
to utilize proper, marine grade connections. The wiring is also
not properly supported and secured, meaning it could easily bounce
into, say, the spinning propeller shaft to the left.
