This year I redid a lot of the wiring in my boat - heavy welding cable between new batteries while they were being replaced as well as rerunning some standard wire to accessories. I'd like to know how many hundreds of feet of cable/wire our members have on board. Its a lot and all of us spend countless hours like a NASCAR team preparing for the next race/tournament.
I came across this wire and used it to replace runs to several of my accessories. Its has positive and negative already bound together in a jacket just like house wiring but its purposely made for marine applications. its saves a lot of time vs. trying to tape up single positive and negative strands.
