Adding a fuse box to the bow of my boat?

Can anyone assist me in the process of wiring a second fuse box. I wish to put one on the bow of my boat so that I don’t have to keep pulling up the floor panel to run wires. Do I just need to run a +/- wire from the cranking battery to the fuse box?

Basically yes, but I would fuse the wire going to the fuse box and use the aproppriate wire size to your new fuse box and then fuse accordingly to your accessories.

You don't need a fuse box, just a terminal block. 1 fused Power wire to feed the terminal block and good ground. Remember the bow of a boat gets wet!

I mounted a fused block to the underside of my front STBD locker lid, then I ran a 12 ga wire from the SWITCHED side of the Starting Battery breaker, (RED) to the POS side of the fuse block and a BLACK wire from the NEG post of the Starting Battery to the NEG connection on the Fuse Block

Then used 14 ga from EACH Graph to its own fused connection on the Fuse Block

14 or 16 from any other powered device. IE: Hydrowave, Ultrex Positioning Puck, etc

Be sure to use stranded copper wire, not solid and not aluminum. Electricity travels on the surface of a wire, and stranded has a lot more surface, plus it is much less prone to metal fatigue breakage from vibration.
