Thread: Is this a good way to wire things?

I have an old 1973 Mon Ark that I have been doing some remodeling on. I don't know a whole lot about wiring and this boat has been wired like this for many years. The first picture is a ground wire that goes to the negative post and it is grounded to the aluminum seat. The second picture is a little fuss box that has an extension cord that goes to the positive post and the wires from it are split to the box. The third picture is how the extension cord connects to the positive on the battery.. Is this a good way to wire things?
